Most of Prof. Järrendahl’s studies are focused on the use of polarized light to investigate structures on the nanometer scale. Often by using spectroscopic ellipsometry combined with other characterization methods such as electron microscopy and X-ray diffraction. The structures can be thin films, multilayers, superlattices, photonic crystals, sculpted films, and/or metamaterials. In most cases, they are artificially produced, but Prof. Järrendahl’s group has also done several studies of layered structures in beetle shells. It can also be added that I get extra excited if the structures are aperiodic or chiral.

Label-free quantitative 3D phase imaging techniques are becoming increasingly important and popular in biological and medical applications for measurements and monitoring of cells, cell cultures and tissues. In particular, the possibility of the quantitative three-dimensional (3D) representation of living samples holds tremendous potential for advancing the field as it would provide unprecedented ease of insight into subtle intracellular mechanisms.

In this talk I will discuss the recent progress and trends in development and applications of 3D QPI systems based on optical diffraction tomography (ODT) with holographic projections. The presentation will focus on algorithms and systems which allow to overcome the most important issues such as: (i) lack of isotropic and sufficiently high spatial resolution essp. in the case of limited angle optical diffraction tomography(ODT), (ii) lack of the chemical specificity (general feature of QPI methods), (iii) multiple scattering which limits the size (thickness) of  investigated samples (tissues, small scale objects) and (iv) lack of efficient solutions for in-vivo tissue investigations (such as in the case of optical coherence tomography (OCT)). The discussed solutions will include utilization of unified k-space theory of OCT which allows to provide an efficient use of combined OCT and ODT approaches, development of multimodal systems combining ODT with fluorescence microscopy and ODT with Raman spectroscopy, as well as applying AI solutions to support better reconstruction of  biophysical parameters of cells and tissues.

However  3D QPI systems to be fully quantitative require proper metrological approach to assess the accuracy and precision of measurement. This problem is most often overlooked in both research and commercial QPI systems and there are no standardized methods for testing and reporting their  metrological performance. Therefore I will also present the methodology for metrological evaluation of 3D QPI instruments for biomedical applications. The methodology entails suitable phantoms, quality assessment metric and easily reproducible protocol that is attainable for both numerical and experimental analysis. We demonstrate its applicability by comparing simulated and physical reconstructions obtained from 3 holographic tomography systems. The results will serve as a reference point for past and future research, encourage to benchmark new systems in a similar manner and further the efforts towards the standardization in 3D QPI metrology.

Morgan Lu is an expert of lighting design and simulation. He has 8 years of experiences in customer support and education of Synopsys LightTools, RSoft DiffractMOD and LucidShape software. He holds Master of Physics degree from National Yang Ming Chiao Tung University. In recent years, Morgan focuses on multi-domain solutions, such as waveguide AR, pancake lens VR, in-display imaging system, diffractive optical element, as well as designing and optimizing complex optical systems by integrating different tools.

With the development of the metaverse, virtual reality (VR) is becoming more and more popular, so the design process for these systems is rapidly evolving. Designing a VR system that features pancake lenses can produce a system with impressive optical performance as well as a competitive advantage in size, weight, and cost.

The main design concept of a pancake lens is a folded ray path where polarized rays reflect between polarization elements. This can be beneficial for increasing the total optical path length within a shorter overall length. In other words, it allows you to decrease the thickness between the display and human eye, which can significantly reduce the volume required for the helmet unit.

A pancake lens system includes three primary parts: a lens module, polarization elements, and human visual components. For the lens module, imaging performance is the most important aspect that needs to be considered and optimized. Precisely simulating image quality and efficiently optimizing with design requirements are key for lens design. For the polarization elements, you must consider the “polarization axis” in the computation. Polarization properties are usually applied to a curved lens surface in pancake lens system, because the polarization axis varies along a curved surface. If you used a flat polarizer, the polarization axis would be the same for each point on the lens surface, and the result would be very different from the curved lens case. Lastly, we must combine all components and check the visualization effect to discover if any anomalies exist. For example, a non-ideal polarization state may cause issues such as leaked rays, flare, or ghost images. These must be identified and reoptimized at a system level.

This talk will introduce an integrated solution to a pancake lens design using Synopsys CODE V, RSoft DiffractMOD RCWA, and LightTools software. CODE V is an imaging design tool for modeling many types of imaging optical systems. We will use it to build a triplet lens and optimize the lens to meet the specifications. RSoft DiffractMOD is an efficient tool for computing periodical structures. In this case study, we will use a wire grid polarizer and retarder modeled in RSoft DiffractMOD to selectively transmit and reflect light. Once we complete the lens design and polarization elements design, the results will be imported into LightTools, where we will model the displays and eye receiver model and perform system simulation. We can also use LightTools features to filter the primary path and unwanted path for stray light analysis. With this seamless cross-product workflow, we can easily achieve the desired performance and reduce stray light impact for this VR system.

We are biomedical optics lab using lasers for the observation of cells in vivo, the sensing of metabolic molecules, the diagnosis of diseases, and the development of medical devices. For the observation, we integrated home-build femtosecond lasers, scanning electronics, and microscopes into an in vivo microscopy system. On this platform, we studied embryonic development, tumor microenvironment, pharmacokinetics of nanomedicines, and in vivo cytometry of leukocytes. For the tracking of cells or drug delivery, we developed multiphoton contrast agents with nanomaterials like Si quantum dots, gold nanorod-in-shell, insulin-gold nanodot, iron oxide, and iron-platinum alloy. Exploiting the laser excited autofluorescence of metabolic molecules, we are developing spectroscopic methods for disease diagnosis. Through the discovery of characteristic optical properties in biomedical context, we aim to develop medical devices to solve the unmet clinical needs.

Morten Ibsen spends much of his time researching Optics, Optoelectronics, Fiber laser, Laser and Optical fiber. His Optics study often links to related topics such as Amplifier. His Optoelectronics research focuses on subjects like Photon, which are linked to Polarization, Quantum optics, Broadband and Birefringence.

The concepts of his Laser study are interwoven with issues in Power, Wavelength, Microfluidics and Zero-dispersion wavelength. The various areas that Morten Ibsen examines in his Optical fiber study include Nonlinear optics and Laser linewidth. His Fiber Bragg grating research is multidisciplinary, incorporating perspectives in Fiber optic sensor and Distributed feedback laser.

Fibre Bragg gratings (FBGs) are well-established all-fibre devices capable of monitoring a range of parameters in various configurations with high precision incl., strain, temperature, and pressure. Due to the ability to accurately design the phase and amplitude response from FBGs into their spatial refractive index profile, and because of the flexibility to precisely control their length, they can also be used as devices to help correct signal distortion encountered in optical transmission systems resulting from, for example, timing- jitter and chromatic dispersion. The precise control of length can also be utilised to monitor and determine perturbations continuously along their length, in real-time. One such application, demonstrated and researched more extensively in recent years, is the ability to monitor and determine the velocity of rapid chemical reactions and detonation events with a very high degree of spatial precision.

The speed at which shock-fronts advance through a material – the velocity of reaction/detonation – is an important measure for assessing the performance and characteristic behaviour of the material. Optical fibre sensors, incl., FBGs, are proving an excellent diagnostic tool for this purpose too, and because of their small size, they can be used as embedded probes offering minimal physical invasiveness into the compounds and materials being tested. In this talk we will review and discuss our research in this area and discuss probes based on both uniform and chirped FBGs, bare fibres, and rare-earth doped fibres. We will discuss how these probes are designed and discuss the advantages and limitations of each of them depending on the exact application and system they are designed for. We will show that using a new approach we developed based on uniform FBGs it is possible to achieve spatial uncertainties below ±10m when determining the position of the perturbation on the FBGs during high-speed events with velocities in excess of ~6mm/s (6km/s).

Various Al atomic contents were doped into HfGaO and were deposited on sapphire substrates at approximately 80 K by using a vapor cooling condensation system. By using energy-dispersive spectrometer measurements, it was found that the Al atomic content in the AlHfGaO films increased with an increase of the deposition temperature of an Al2O3-powder- loaded tungsten boat. AlHfGaO films with an Al atomic content of 3.16% had a higher optical bandgap energy (5.36 eV) than did undoped HfGaO films (5.14 eV). Increasing the Al atomic content reduced the Ga atomic content; however, the Hf atomic content was similarly unchanged, which revealed that the Al dopants substituted Ga atoms. By using X-ray photoelectron spectroscopy measurements, it indicated that the oxygen vacancy defects in HfGaO films were suppressed by doping with Al to produce AlHfGaO films. These results verified that the Al doping of HfGaO films could effectively modify the bandgap energy and could suppress oxygen vacancy defects.

The AlHfGaO films with various Al atomic contents were used as the channel layers of ultraviolet phototransistors. The undesired oxygen vacancy defects residing in the AlHfGaO films could be compensated and suppressed by doping Al dopants. In addition to modulate the cutoff wavelength of the ultraviolet phototransistors by doping various Al atomic contents in the AlHfGaO channel layers, the performances of the resulting phototransistors could be improved due to the reduction of the amount of oxygen vacancy defects. Compared with the phototransistors using the HfGaO channel layer, when the phototransistors using the AlHfGaO channel layer with an Al atomic content of 3.16%, its cutoff wavelength was shifted from 240 to 225 nm, and the detectivity was improved from 1.62 × 1012 to 3.16 × 1012 Jones. Besides, the photoresponse speed was also improved by increasing Al atomic content in the AlHfGaO channel layer of the phototransistors.

The contrast or signal-to-noise ratio (SNR) the most crucial and fundamental parameter in an optical sensing system. It’s immediately related with the quality of sensing. In an imaging system, with a better image contrast/SNR, the imaging system can be performed at a faster frame rate or deeper tissue locations without compromising image quality.

In this talk, the recent studies of our group on the contrast enhancement in femtosecond laser based optical sensing/imaging systems will be presented by the higher-order-modulations or the carrier pulse-stretching. These optical or electrical-optical methods will largely enhance the contrast in the coherent and in-coherent nonlinear laser scanning microscopes. Significant background reduction together with the SNR enhancement will presented in the second-harmonic generation microscopy on collagen fibrils or the two-photon fluorescence microscopy on whole drosophila brains.The fundamental working principles, experimental design, various results on the femtosecond sensing with enhanced contrast, and the future perspective/possibility for these technique will be also presented.
