Abstract :
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.
