We report on the design, fabrication and characterization of a monolithic(a1ly integrated InP/InGaAs PIN/HBT-Photoreceiver for a wavelength of X = 1.55pm. The three-stage-amplifier achieves a transimpedance of 54.5dBR (5300) and the optical/electrical-3dB-bandwidth of the entire receiver is 23GHx. This corresponds to a transimpedance-bandwidth product olf 12THxR, which is one of the highest values published to date.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
