摘要： An optical receiver module includes: a lens array including a plurality of condenser lenses arranged in one direction to define a plane with optical axes in parallel to each other; and a light receiving element array including a plurality of light receiving elements each configured to receive light emitted from each of the condenser lenses. The light receiving element array includes: a semiconductor substrate to which the light from each of the condenser lenses is input and through which the light is transmitted; and light receiving portions each configured to receive the light transmitted through the semiconductor substrate and convert the light into an electrical signal. A shift of the optical axis of each of the condenser lenses from a center of each corresponding one of the light receiving portions is larger in a direction perpendicular to the one direction within the plane than in the one direction.

摘要： An optical module includes a semiconductor optical device in which an active layer located at one side, an electrode located at the same side, and a mirror that reflects light toward the side opposite the electrode are monolithically integrated, a sub-mount having one surface on which a first wiring pattern is formed, a substrate in which an optical waveguide and a grating coupler are formed in a surface layer of the substrate, a spacer having an upper surface on which a second wiring pattern is formed, and a wire. The sub-mount is mounted on the spacer. The first wiring pattern on the sub-mount faces part of the second wiring pattern on the spacer and is electrically connected thereto. The second wiring pattern on the spacer includes a pad being disposed in a region exposed from the sub-mount and being bonded to the wire.

摘要： An optical device includes a first substrate, having first and second surfaces, and a second substrate having a third surface. The first substrate includes: a laser unit, having an active layer and emitting light into the first substrate from the active layer; a reflecting mirror, having a plane obliquely intersecting an optical axis of light emitted from the laser unit, and being formed on the first surface so as to reflect the light toward the second surface; and a convex lens, being formed in a region on the second surface, the region including an optical axis of the light reflected by the reflecting mirror. The second substrate is provided with a grating coupler and an optical waveguide on the third surface, the optical waveguide having light incident on the grating coupler propagating therethrough.
