Abstract
A double heterojunction bipolar transistor on a substrate comprises a collector formed of InGaAsP, a base in contact with the collector, an emitter in contact with the base, and electrodes forming separate electrical contacts with each of the collector, base, and emitter, respectively. A device incorporates this transistor and an opto-electronic device optically coupled with the collector of the transistor to interact with light transmitted therethrough.
