“…Traditionally, such front-end circuits are implemented using III-V technologies due to their speed and noise advantages. There have been plenty of integrated circuits/devices implemented in III-V, Si Bipolar and SiGe technologies for 10Gb/s optical communication applications [30][31][32][33][34][35][36]. With these high-performance technologies, optical circuits/devices for even higher data rate operations (e.g.…”
