Patent ID: 8277131

Claim:
A semiconductor optical communication module comprising: a carrier having a first edge and a second edge opposite the first edge; a lens assembly having an end parallel to and facing the first edge of the carrier; and a semiconductor chip mounted on the carrier, the semiconductor chip including a first facet oriented at an acute angle relative to the first edge, a second facet opposite the first facet, a light emitting element for generating an optical signal, a modulating element for modulating the optical signal, a connecting optical waveguide for transmitting the optical signal generated by the light emitting element to the modulating element, and a bent internal optical waveguide for transmitting the modulated optical signal, the optical signal transmitted from the bent internal optical waveguide propagating on an optical axis extending from the first facet to the end of the lens assembly, the optical axis being orthogonal to the end of the lens assembly and the first edge of the carrier; a straight signal line for transmitting an electrical modulating signal, the straight signal line extending from the first edge to the second edge on an upper surface of the carrier, the first facet being closer than the second facet to the signal line; and a wire for conducting the modulating signal from the straight signal line to the modulating element.
