An optical module includes: a photonic device emitting or receiving a light wave; an optical waveguide for transmitting the light wave; a lens focusing the light wave; a mirror for changing a traveling direction of the light wave to optically couple the photonic device with the optical waveguide; a manipulation lever for manipulating an orientation of the mirror; a support spring for supporting the mirror; and a substrate integrated with the mirror, the manipulation lever, and the support spring. The support spring couples the mirror with the substrate so as to allow the mirror to change the orientation thereof with movement or rotation along at least two axes. The manipulation lever extends from the mirror in a direction in which the manipulation lever avoids approaching the optical waveguide.

The second wiring pattern includes extended regions from the main body side to the projecting portions as seen in a direction in which the pair of leads extend, and wiring regions continuously spreading from the extended regions in a direction away from the main body. Supposing that a length of the wiring region from an end of the projecting portion as a reference point to a farthest position in a direction away from the main body is a first width and a width of the extended region in a direction parallel to a side opposed to the main body side through the end of the projecting portion is a second width, the first width is smaller than the second width. The second insulating substrate is sandwiched between the second wiring pattern and a base, and thereby, a capacitance is formed.

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.


Provided is a semiconductor optical device, an arrayed semiconductor optical device, an optical module having a structure to reduce the parasitic capacitance as well as a high design degree of freedom and having a multilayer structure in which a semi-insulating substrate, a first semiconductor layer having one conductive type, an active layer having light emission function, a second semiconductor layer having the other conductive type, an insulating layer, and a conductive layer are stacked in order from the bottom. The multilayer structure includes a light emitting structure, a first electrode structure, and a second electrode structure. In the semi-insulating substrate and the first semiconductor layer, a first grove which separates the second electrode structure from a remaining portion and approaches the second electrode structure with a non-linear shape rather than a linear shape in its entirety is formed.

A plurality of leads include a pair of differential signal leads for inputting differential signals, and a power supply lead for supplying power. A wiring pattern includes a pair of differential transmission lines connected to the pair of differential signal leads, and a power supply wiring connected to the power supply lead. A wiring board includes a first region overlapping an optical subassembly, and a second region extending from the first region so as to protrude from the optical subassembly. The pair of differential signal leads are farther away from the second region than the power supply lead. The pair of differential transmission lines are close together so as to be electromagnetically coupled to each other. The optical subassembly does not include a lead penetrating the wiring board in a region between the pair of differential transmission lines.
