Abstract
An optical module having an improved thermal condition around a light-emitting device is provided. The optical module includes the light-emitting device, a substrate on which a driver circuits connected to the converting device is mounted thereon, a base for securing the substrate and the light-emitting device, a thermal block for dissipating heat generated by the driver circuits, and a cover. The base has an opening into which the thermal block is arranged so as to be in contact with the driver circuits, whereby heat generated by the circuits enables to transmit to the cover through the thermal block.
Claims6
An optical module, comprising:
- an optical subassembly including a semiconductor optical device;
- a substrate securing the optical subassembly and mounting a circuit for driving the semiconductor optical device, the circuit generating heat;
- a base enclosing the optical subassembly, the base providing an opening for exposing the circuit;
- a cover made of metal;
- and
- a thermal block for dissipating the heat generated by the circuit, the thermal block arranged so as to lid the opening of the base and being thermally in contact with the circuit and the cover.
