In0.52Al0.48As Based High-Speed and Wide Dynamic Range Avalanche Photodiode for Coherent Lidar Application
Naseem .;Yan-Min Liao;Jin-Wei Shi
A high-sensitivity and a high-power photo-receiver is preferred in coherent lidar system. In this work, we demonstrate top-illuminated APDs, which can simultaneously exhibit low excess noise (k<0.14) and wide 3-dB bandwidth (16GHz) with high responsivity (5.8A/W) under the operation at saturation output (5 mA).

Monolithically Integrated Opto-Electronic SR Latch Using Light Emitting Transistors
Ya-Ting Liang;Yun-Ting Huang;Chao-Hsin Wu
We have developed an opto-electronic SR latch using light-emitting transistors (LETs) on a GaAs substrate via a monolithically integrated fabrication process. Taking advantage of dual-output (electrical and optical) characteristics, it can transmit or store information more efficiently and be applied to build opto-electronic integrated circuits (OEICs).

Towards 1.25 Gbit/s High-Speed Green InGaN/GaN Micro-Light-Emitting Diodes Array for Wireless Optical Communication
Fang-Jyun Liou;Guan-Hao Chang;Yu-Chien Hsu;Hsin Chiang;An-Chen Liu;Sung-Wen Huang Chen;Hao-Chung Kuo
Semipolar (20-21) micro-LEDs were manufactured using improved epitaxy and chip process approaches. The highest modulation bandwidth up to 1.125 GHz and 1.25 Gbit/s data rate was achieved with a high polarization ratio. These results suggested an excellent transmission capacity of green semipolar (20-21) μLEDs in visible light communication (VLC) applications.

Photonic Integration of EAM and SOA by Quantum well intermixing through High Oxygen Content Dielectric Film
Yen-Hsiang Chang;Yi-Jen Chiu
Impurity-Free Vacancy Diffusion (IFVD) quantum well intermixing was performed in high oxygen concentration SiOx through SCF treatment, enabling the photonic integration. Electroabsorption modulators (EAM) integrated semiconductor optical amplifier (SOA) were fabricated, realizing 10dB extinction ratio and optical gain of 11 dB.

Single-Mode High-Speed 850 nm VCSEL Operated at 50 Gb/s for Pre-emphasis NRZ-OOK after 100-m GI-SMF transmission
Dong Yang;Guan-Hao Chang;Hsien-Yao Tseng;Shu-Wei Chang;Hao-Chung Kuo
In this study, a single mode and high speed vertical-cavity surface-emitting laser (VCSEL) is designed and fabricated. The device exhibits 26.5 GHz 3-dB E-O bandwidth and 50 Gb/s for pre-emphasis NRZ-OOK transmission in back-to-back and 100m GI-SMF links with eye-opening, which is extremely fast for single mode 850nm VCSELs.

2D Beam Steering through Silicon Ribbon Grating Array
Hsun-Yuan Chi;Ting-Sheng Lin;He Jhang;Jhih-Jia Kang;Shih-Hsiang Hsu
A silicon ribbon grating array with variable linewidths on the dual-beam optical phase array is designed and demonstrates the horizontal and vertical scanning ranges as 90 and 30 degrees, which is superior to the previous dual-beam system. The grating lobe and crosstalk are reduced by nearly 6-dB and 3-dB, respectively.
