1.5-Gbit/s Filter-free Optical Communication Link based on Wavelength-selective Semipolar () InGaN/GaN Micro-photodetector

Abstract
We report on wavelength-selective semipolar (2021) InGaN/GaN micro-photodetector with broad modulation bandwidth of 293.52 MHz, outperforming polar-based devices. A 1.5-Gbit/s data rate was achieved without the need of spectral-efficient modulation format.
