Low-Loss Ultra-Thin Si/Si3N4 Composite Photonic Waveguide
The Anh Nguyen;Ming-Chang M.Lee

We present an ultra-thin Si/Si3N4 composite waveguide structure equipped with
asymmetric dual-level grating couplers. This waveguide is capable of implementing low-loss
and high-speed photonics integrated circuit

FMCW Lidar system with performance comparison using P-i-n PD and Avalanche Photodiode receivers at 1550nm wavelength
Zohauddin Ahmad;You-Chia Chang;I-Sheng Kuo;Rui-Lin Chao;Yung-Jr Hung;Huang-Ming Chen;Jyehong Chen;Jin-Wei Shi

We demonstrate an electrical based FMCW lidar system and the performance was compared with the different receiver end consisting of APD and commercial available p-i-n PD based photo-receiver (p-i-n+TIA) both integrated with the LNA. APD receiver have around 7 dB larger S/N ratio in each pixel of image captured.

Using Organic Photovoltaic Cell Receiver and Linear Regression Machine Learning Algorithm in Visible Light Positioning (VLP)
Shao-Hua Song;Dong-Chang Lin;Yun-Shen Lin;Chong-You Hong;Yu-Chun Wu;Hsin-Fei Meng;Chien-Hung Yeh;Chi-Wai Chow

We demonstrate a visible-light-positioning (VLP) system using organic-photovoltaic-cell (OPVC) and linear-regression-machine-learning (LRML) algorithm. Interpolation is proposed and employed to reduce the amount of training data, while the VLP performance can be maintained.

Optical spot size converter integrated III-V active devices and SOI through adhesive bonding technique
JyunYe Chu;Yi-Jen Chiu

An adhesive material-assisted wafer bonding was used to integrate Ⅲ-Ⅴ quantum well-based devices on a low-loss silicon on insulator (SOI). An optical spot size converter (SSC) defined by tapered waveguide was designed for optical interconnection between two material templates. A function of EAM-SOA integration on SOI was successfully demonstrated.

Using Gaussian Filtering and Polynomial Curve Fitting to Improve Signal Decoding in Optical Camera Communication (OCC)
Saswati Barat;Chi-Wai Chow

We propose and demonstrate using Gaussian-filtering and polynomial-curve-fitting to improve signal decoding in optical camera communication (OCC). Experimental result shows that the proposed scheme can improve the bit-error-rate (BER) performance.

Multimode Silicon-on-Insulator (SOI) Waveguide Grating Coupler based Mode Multiplexer and Demultiplexer for Few Mode Fiber (FMF) Transmission
PinCheng Guo;JuiFeng Tsai;ChunJui Chen;ChingWei Peng;GuanHong Chen;Chien-Hung Yeh;Yeyu Tong;HonKi Tsang;ChiWai Chow

We demonstrate a silicon-on-insulator (SOI) based multimode-waveguide-grating-coupler (MWGC) for simultaneously mode multiplexing/demultiplexing 2 fiber-modes at 2 polarizations, including LP01x, LP11x, LP01y and LP11y into a few-mode-fiber (FMF) transmission. 190-Gbit/s data transmission is achieved.

A Bidirectional Fiber-FSO-5G Wireless Convergence System
Yu-Ting Huang;Cing-Ru Chou;Yi-Hao Chen;Hai-Han Lu

A bidirectional FSO-5G wireless convergence system with a VCSEL-based wavelength selector and a remotely injection-locked DFB LD is demonstrated.It exhibits an excellent convergence not only due to its development for incorporating optical fiber with optical/5G wireless networks, due to its enhancement for two-way high-speed and long-haul communications.

Sub-wavelength Channel Waveguides with Near-Zero Flattened Dispersion for Silicon Photonics Applications
Yu-Ting Lai;YI-JANG HSU;Hsuan-Ming Kuo;Shi-Chieh Hsu;Yinchieh Lai

We propose a new type of channel waveguides with a sub-wavelength structure such that low and flattened dispersion can be achieved on the silicon-on insulator platform at 1.55μm wavelength. The structured waveguide is functional complete for designing basic components such as the directional couplers and ring resonators.
