Siti Sulikhah Novel Lateral Silicon GACC Structure in Hybrid Active III-V on Standard SOI Photonic Devices
Ika Novitasari;Siti Sulikhah;San-Liang Lee

This study investigates a lateral silicon GACC structure that allows efficient and alignment tolerant mode conversion between an active III-V waveguide and a-Si waveguide with a standard SOI platform, where the two group waveguides are bonded together with an adhesive material. By using the 3D-FDTD simulation, the coupling efficiency can be achieved up to 78.5% at 1550 nm with 20-nm wavelength bandwidth, respectively.

Ching-Chieh Hung Liquid crystal loaded Mach-Zehnder Interferometer optical switch based on silicon nitride waveguides
Ching-Chieh Hung;Chun-Ta Wang

In this work, we demonstrated a LCs-loaded MZI optical switch based on silicon nitride waveguides. After applied a driving voltage, the light is switched from the cross port to the bar port over a broadband ranging from 1450 to 1650 nm.

Hung-Ching Chung Broadband Silicon Polarization Splitter-Rotator using Multi-Wavelength Adiabaticity Engineering
Hung-Ching Chung;Guan-Xun Lu;Shuo-Yen Tseng

We use multi-wavelength adiabaticity engineering in asymmetrical directional couplers to design a broadband silicon polarization splitter-rotator. A 141 um-long device exhibits excellent performance with >97% transmission and >16 dB extinction ratio over a bandwidth of 300nm.

Tien-Wei Yu Design of Silicon Photonics Zigzag Structured Metasurface Mode Converter Using Genetic Algorithm (GA) for Optimization
Tien-Wei Yu;Tun-Yao Hung;Pin-Chen Kuo;Ching-Wei Peng;Guan-Hong Chen;Chien-Hung Yeh;Chi-Wai Chow

We illustrate a design of silicon photonics (SiPh) zigzag structured metasurface mode converter from fundamental TE0 mode to first-order TE1 mode using genetic algorithm (GA). The device is compact with a high transmission of 85% at wavelength of 1550 nm.
