Silicon Waveguide Integrated with Germanium Photodetector for a Photonic-Integrated FBG Interrogator

We report a vertically coupled germanium (Ge) waveguide detector integrated on silicon-on-insulator waveguides and an optimized device structure through the analysis of the optical field distribution and absorption efficiency of the device. The photodetector we designed is manufactured by IMEC, and...
