Abstract
EA bidirectional optical semiconductor apparatus of the present invention includes: a substrate embedding an optical waveguide, through which output light and input light are propagated; a semiconductor light-emitting device for emitting the output light toward one end of the optical waveguide; an optical branching filter, provided in the optical waveguide, for transmitting at least part of the output light and guiding at least part of the input light to the outside of the optical waveguide; a semiconductor light-receiving device, provided over the substrate, for receiving the input light guided by the optical branching filter to the outside of the optical waveguide; and a light-blocking member, formed on the surface of the semiconductor light-receiving device, for blocking the light emitted from the semiconductor light-emitting device.
