| Abstract(in English) | Optical receivers for 400 Gb/s and beyond optical communication systems have been required modulation speeds higher than 50 GBaud in either case of intensity modulation direct detection(IMDD) or coherent transmission applications. Furthermore, the expectations for higher performance toward 100-GBaud-class are also growing. The InP-based waveguide photodetector consisting of the butt-joint optical coupling structure is very promising. As structural advantages, it allows wide bandwidth operation while suppressing the trade-off with responsivity. In addition, it also gives high linearity, which is indispensable for detection of multilevel signals such as pulse amplitude modulation (PAM) and quadrature phase amplitude modulation (QAM). In this report, focusing on the achievements that we have ever engaged, we elaborate on wide bandwidth and high responsivity of InP-based waveguide photodetectors integrated with the 90??hybrid for coherent receivers, and also introduce the waveguide avalanche photodiodes (APDs) for IMDD receivers. |
