A three-terminal, monolithically integrated device is presented combining both power generation and optical communication at 1.55 µm. A discrete InP cell without an anti-reflection coating with an AM0 efficiency of 12.8 % and an InGaAs/InAlAs electroabsorption modulator with a peak ON/OFF ratio of 3.0 have been developed. A monolithic device has been grown and fabricated, and is undergoing simultaneous PV collection/free space optical communication testing.
