Abstract
A new SiGe heterojunction bipolar phototransistor (HPT) based on a commercially available process was designed, realized, and experimentally characterized. Its internal characteristics, mainly the collector-to-base capacitance, vary significantly with the received light power, making it suitable as an active element of a light-controlled photo-oscillator. It can also be a key component of optical network-on-chip (ONoC). Its responsivity was improved and its transition frequency remains in the range of 30 GHz.
