Cryogenic Oxide-VCSELs for 4K Optical Data Link
Milton Feng, Haonan Wu, Wenning Fu, Derek Chaw, University of Illinois at Urbana-Champaign (USA)
The rise of the Internet and AI has led to a spike in demand for computational resources and cloud services. High-speed and power-efficient superconducting processors based on single flux quantum (SFQ) technology at 4 K and fiber data transferring in quantum computing can be a viable solution. In this work, the high-speed optically packaged oxide-VCSELs operated down to 2.9 K are reported with the record speed of 54 Gbps NRZ and 100 Gbps PAM-4 data transmission. Furthermore, a superconducting processor for directly modulating an oxide-VCSEL coupled with OM4 fiber is demonstrated for 20 Gb/s NRZ for 4K full data link.

Lithium niobate is a popular material in integrated photonics due to its optical and electro-optic properties. It is used in low-loss waveguides for high-speed and high integration density photonic devices. This technology enables integration of various devices on a single chip for quantum technology and telecom applications. Here, we present waveguide devices such as modulators, micro-ring resonators and frequency converters having losses below 0.1 dB/cm. The challenges of wafer-scale fabrication will also be discussed.

Silicon photonics enabled multi-function integrated optic circuit with hybrid III-V photodiode for miniaturized fiber optic gyroscope
Yu-Yun Tzeng, Ting-Hsuan Kuo, Tzu-Jung Kuo, Sin-Yun Lu, Wei-Xuan Chen, Yen-Chieh Wang, Liang-Xuan Lan, Yung-Jr Hung, National Sun Yat-sen University (Taiwan)
We demonstrate a fiber optics gyroscope by employing a silicon photonics multi-function integrated optical circuit with hybrid integrated photodiode on top of grating coupler. This approach enables a high polarization extinction ratio of 51.3 dB when the light propagates from fiber coil to the photodiode, thus enables tactical-grade gyroscope performance.

Adiabaticity engineered silicon polarization independent directional coupler for the O-band
Yu-Fang Lo, Hung-Ching Chung, Shuo-Yen Tseng, National Cheng Kung University (Taiwan)
Applying multi-parameter adiabaticity engineering protocol (MPAE), we propose a broadband and polarization independent directional coupler on silicon-on-insulator (SOI) platform. The simulation shows that when the coupling length of the designed coupler is 273 μm, the coupling efficiency is higher than 99% for both TE and TM mode at a wavelength of 1310 nm. It also exhibits high wavelength tolerance of 200 nm and presents ultra-low IL and large ER within the optical range.

A novel artificial intelligence assisted laser-heated pedestal growth system (AI-LHPG) for fabricating a 300-nm broadband single-mode Cr-doped crystalline core fibers (SMCDFs) are demonstrated. This SMCDF with 12-μm core diameter and a 20-cm fiber length shows the gross gain was 18.04-dB at 1550-nm wavelength.
