A 82-GHz-Optical-Gain-Cutoff-Frequency InP/InGaAs Double-Hetero-structure Phototransistor (DHPT) and Its Application to a 40-GHz-Band OEMMIC Photoreceiver

This paper presents an ultra-high-speed InP/InGaAs double-heterostructure phototransistor (DHPT) with a record optical gain cutoff frequency of 82 GHz and a 40-GHz-band OEMMIC photoreceiver based on a DHPT/DHBT structure. The 40-GHz operation frequency is also the highest reported for monolithically integrated HPT/HBT photoreceivers.
