Maximal-Ratio Combining for Spatial Diversified Rx in Free Space Optical Communication
Tzu-Chieh Wei, Yun-Han Jian, Chih-Chun Wang, Chi-Wai Chow, National Yang Ming Chiao Tung University (Taiwan); Chien-Hung Yeh, Feng Chia University (Taiwan)
The maximal-ratio-combining (MRC) algorithm is demonstrated in a single-input-multi-output (SIMO) free-space-optical communication (FSOC) system with two receivers (Rxs). 1.4-dB gain is achieved at the forward-error-correction (FEC) threshold.

Optimization of Differential-Phase-Shift Quantum Key Distribution for Enhanced Key Rate
Wei-Rong Zhuo, Ming-Sheng Chen, Yuh-Renn Wu, National Taiwan University (Taiwan)
In this research, we employed a well-established discrete event simulator to modularize the DPS QKD configuration. The modular simulator allowed us to analyze the impact of the clock rate and the dead time of a single photon detector on the key rate at different communication distances. Through this investigation, we gained insights into achieving improved key rates in practical QKD systems while considering cost-effectiveness. Additionally, we investigated the influence of the number of pulses in each block during QKD transmission on the key rate and quantum bit error rate, followed by proposing optimization results for maximizing the key rate.

Experimental Demonstration of 100-m Free-Space Optical Communication (FSCO) for Mobile Mid/Front-Haul in Cloud Radio Access Network (C-RAN)
Chih-Chun Wang, Yin-He Jian, Tzu-Chieh Wei, Tun-Yao Hung, Jian-Wen Chen, Jia-Fu Li, Ming-Chieh Tsai, Chi-Wai Chow, National Yang Ming Chiao Tung University (Taiwan); Chien-Hung Yeh, Feng Chia University (Taiwan)
We experimental demonstrate and characterize a 100-m free-space-optical-communication (FSOC) for the mobile mid/front-haul in cloud-radio-access-network (C-RAN). 37.58 Gbit/s/λ transmission link is achieved fulfilling the pre-forward-error-correction bit-error-ratio (pre-FEC BER = 3.8 × 10−3).

200 Gbit/s/λ High Speed PAM4 Signal Processing using MZI-based Optical Neural Network (ONN)
Tun-Yao Hung, Ching-Wei Peng, National Yang Ming Chiao Tung University (Taiwan); David W.U Chan, Chinese University of Hong Kong (Hong Kong); Pin-Cheng Kuo, Guan-Hong Chen, Chi-Wai Chow, National Yang Ming Chiao Tung University (Taiwan); Chien-Hung Yeh, Feng Chia University (Taiwan); Hon Ki Tsang, Chinese University of Hong Kong (Hong Kong)
We propose an optical-neural-network (ONN) to classify 4-level-pulse-amplitude-modulation (PAM4) with high intersymbol-interference (ISI), which was experimentally generated by silicon-microring modulator (SiMRM) of ~47-GHz bandwidth. Result shows that soft-decision-forward-error-correction (SD-FEC) is achieved at 200 Gbit/s transmission.

High-Speed 106.25 Gb/s VCSELs for 800G Datacom and Telecom Applications
Chih-Chuan Chiu, Yun-Cheng Yang, Wei-Hsin Chen, Guei-Ting Hsu, Chao-Hsin Wu, National Taiwan University (Taiwan)
In this letter, we review the advancement of oxide-confined VCSELs in the context of both 25 Gb/s and 50 Gb/s datacom applications. Additionally, we delve into essential attributes for 800G Ethernet applications, mandating VCSELs to perform at data rates of 56 Gb/s in NRZ modulation and 106 Gb/s in PAM-4 modulation. Furthermore, we present the successful demonstration of a VCSEL boasting a remarkable bandwidth of 33.4 GHz and an impressively low RIN of -150 dB/Hz. This achievement culminates in the realization of single-channel 106.25 Gb/s transmission.
