ABSTRACT

An optical electro-absorption modulator (100) includes a first graphene layer (141), a second graphene layer (142), a ridge optical waveguide (124, 150) formed on the upper surface of a semiconductor layer 120, a first electrode (161) on the first graphene layer (141) and a second electrode (162) on the second graphene layer (142). The first graphene layer (141) and the second graphene layer (142) are formed on the upper surface and the side surfaces of the ridge optical waveguide (124, 150) and are mutually separated.
