Abstract
InP/GaAs heterojunction phototransistors are reported with high DC gain (greater than 270) and high unity-gain frequency (greater than 30GHz). To the authors´ knowledge, these are the highest performance heterojunction phototransistors reported to date. This performance is achieved by a combination of edge-coupled optical access and a two-terminal, optically-biased design. This design allows efficient, small area devices with low parasitics to be produced with a simple fabrication scheme.
