Abstract
Provided is an optical device including a base wafer containing silicon, a plurality of seed crystals disposed on the base wafer, and a plurality of Group 3-5 compound semiconductors lattice-matching or pseudo lattice-matching the plurality of seed crystals. At least one of the Group 3-5 compound semiconductors has a photoelectric semiconductor formed therein, the photoelectric semiconductor including a light emitting semiconductor that emits light in response to a driving current supplied thereto or a light receiving semiconductor that generates a photocurrent in response to light applied thereto, and at least one of the plurality of Group 3-5 compound semiconductors other than the Group 3-5 compound semiconductor having the photoelectric semiconductor has a heterojunction transistor formed therein.
