Silicon photonics (SiPh) has emerged as a promising technology for photonic integrated circuits (PICs). One of the basic components in SiPh is directional coupler (DC), which plays an important role signal monitoring with requirement low wavelength dependence and loss. This paper proposes broadband low-loss DC designed power tapping on 3 μm silicon-on-insulator (SOI) waveguide platform. By utilizing advantages multi-micron waveguides replacing one straight optimized arc-shaped coupling...
Silicon photonics is considered to be an ideal solution as optical interconnect in radiation environments. Our previous study has demonstrated experimentally that responses of device are related waveguide size, and devices with thick top silicon layers expected less sensitive irradiation. Here, we design radiation-resistant arrayed gratings Mach-Zehnder interferometers based on silicon-on-insulator 3 µm-thick platform. The exposed 60Co γ-ray irradiation up 41 Mrad(Si) 170-keV proton total...
In this work, a vertical N-I-P germanium (Ge) photodetector (PD) with multi-mode waveguide input is presented. The fabricated devices exhibit low dark current of 10 nA at bias −1 V, and high responsivity exceeding 0.75 A/W over the wavelength range from 1270 to 1350 nm. High-frequency characteristics measurements show that has 3 dB opto-electrical (OE) bandwidth 23 GHz under −3 V bias, which can be further improved by optimization configuration. A 50 Gb/s clear eye diagram non-return-to-zero...
An optical coupling interface is a crucial component in Silicon Photonics (SiPh) technology for signal transmission. It widely utilized to achieve on-chip light sources and input/output SiPh chips. In this work, we report with focusing structure based on the 3μm SOI waveguide platform minimize mode profile mismatch, resulting high efficiency relatively large -1dB alignment tolerances across wide bandwidth. Simulation results show that our design achieved transmission of greater than -0.85dB...
Optical properties of Mach-Zehnder interferometer and Arrayed Waveguide Grating under 60 Co γ-ray proton irradiation are investigated. Wavelength MZI blueshifts, the shift increases with increasing dose due to an effective refractive index change 10 -4 .
