Free-spectral-range insensitive silicon Mach–Zehnder interferometer for dense wavelength division multiplexing
Cheng-Hsuan Wu;Zhan-Wen Song;Tzu-Hsiang Yen;Yung-Jr Hung Hung
A free-spectral-range insensitive silicon MZI design is proposed and experimentally demonstrated for the first time on silicon-on-insulator. The idea is to compensate for the group index change of silicon waveguide against manufacturing linewidth variability. Experiments reveal a ten-fold improvement in terms of FSR deviation against the fabrication error (7.6 GHz → 0.68 GHz) and a two-fold improvement in terms of the FSR slope (-0.0084/THz → -0.0036/THz), revealing the efficacy of the proposed MZI design.

Compact Silicon Photonics Polarization Splitter and Rotator (PSR) Based on Asymmetrical Directional Coupler and Adiabatic Step Waveguide Taper
Tun-Yao Hung;Pin-Cheng Kuo;Ching-Wei Peng;Guan-Hong Chen;Chien-Hung Yeh;Chi-Wai Chow
We propose and demonstrate by simulation a compact silicon-photonics (SiPh) polarization splitter and rotator (PSR) by utilizing asymmetrical-directional-coupler (ADC) and adiabatic-step-waveguide-taper (ASWT). The whole device is < 90 μm and the polarization extinction ration is > 18 dB in 1540 nm - 1570 nm window.

Dual Mach-Zehnder Interferometers with New Positioning Algorithm
Cheng-Yu Hsieh;Yung-Cheng Hsu;Ting-Wang Cheng;Likarn Wang
A new type of dual Mach-Zehnder interferometer (DMZI) scheme is presented for the first time without using any polarization control method to eliminate the polarization induced fading usually encountered in fiber-optic intrusion detection systems that use DMZIs. A new algorithm for positioning the intrusion-induced disturbance on the fiber is presented.

High-power broadband high-extinction ratio polarization III-V super-luminescent diode coupled to a Si waveguide in Si photonics template
Chen Yu Weng;Yi Jen Chiu
A high-power, broadband, and high-extinction ratio polarization (TE/TM) super-luminescent diode (SLD) coupled to a Si waveguide through grating coupler has been demonstrated in silicon photonics. Using highly compressive-strain multiple quantum wells as active region, SLD waveguide integrated with a slanted reflection mirror was bonded on a silicon grating coupler, attaining 2mW output power and >15dB extinction ratio.

106Gb/s Modulation Speed Cascaded Integration of EAM-SOA using Quantum Well Intermixing technology
Wang Zhen-Hua;Yen-Hsiang Chang;Yang-Jeng Chen;Rih-You Chen;Po-Wei Huang;Chiu Yi-Jen
Cascaded electroabsorption modulators (EAM) integrated semiconductor optical amplifier (SOA) is demonstrated by quantum-well-intermixing technique. Cascaded high impedance transmission lines (HITL) are interconnected with segmental EAM for enhancing impedance match for the output loaded electrode, leading to 106Gb/s PAM 4, -3dB bandwidth of >60GHz and optical gain of >10dB.
