23 GHz monolithically integrated InP/InGaAs PIN/HBT-receiver with 12 THz/spl Omega/ gain-bandwidth product

摘要

We report on the design, fabrication and characterization of a monolithically integrated InP/InGaAs PIN/HBT-photoreceiver for a wavelength of /spl lambda/=1.55 /spl mu/m. The three-stage-amplifier achieves a transimpedance of 54.5 dB/spl Omega/ (530 /spl Omega/) and the optical/electrical -3dB-bandwidth of the entire receiver is 23 GHz. This corresponds to a transimpedance-bandwidth product of 12 THz/spl Omega/, which is one of the highest values published to date.
