摘要： This invention provides an optical transmitter in which reduced power consumption is achieved by, when a signal generator needs data transmission, driving a laser emitting device to perform emission. An optical transmitter includes a receiver, a laser driving circuit, a light emitting unit constituted by a plurality of laser emitting devices, and an EDID memory. The receiver and the laser driving circuit are supplied with power from a dedicated external power supply through a power-supply line, and the power-supply line is provided with a switch. The contact of the switch is controlled to open and close based on a power-supply voltage supplied from the DDC controller to the EDID memory.

摘要： The invention provides an optical module, in which a surface-emitting laser and an optical fiber are coupled, with the optical axes thereof crossed at a predetermined angle, at low cost. A supporting member supports the end of an optical fiber, in which the extending direction of a through hole and a face at the optical fiber end are orthogonal to each other. A surface-emitting laser and the supporting member are coupled by metal projections having different heights, so that a light-emitting face of the surface-emitting laser and the face of the supporting member are disposed so as to be opposed to each other at a predetermined angle. After the projections are formed on an electrode and metal patterns on the surface of the surface-emitting laser by a method based on wire bonding, the leading ends thereof are fixed to metal patterns of the supporting member by ultrasonic welding.

The present invention also provides a manufacturing method therefor and an optoelectric integrated circuit using the surface emitting laser and the photodiode. Semiconductor stacked layers stacked on a semiconductor substrate have a light emitting portion and a reinforcing portion formed with a recessed portion provided therebetween, and a p-type ohmic electrode and an n-type ohmic electrode are formed on the top of the reinforcing portion. The p-type ohmic electrode is electrically connected to a p-type contact layer through a contact hole vertically formed in polyimide buried in the recessed portion to permit supply of a current to the light emitting portion in the thickness direction. The recessed portion has a groove formed to reach the semiconductor substrate, thereby suppressing the parasitic capacity between the p-type ohmic electrode and the n-type ohmic electrode.
