Optical module having an improved heat dissipation and reduced mechanical distortion

Abstract

An optical module includes a heat sink, a cooling device provided on the heat sink, an optical semiconductor device provided on the cooling device, a frame provided on the heat sink adjacent to the cooling device and the optical semiconductor device, an optical system held on the frame in an optical coupling with the optical semiconductor device, and a cover member provided on the frame so as to define a hermetically sealed enclosure together with the frame and the heat sink, wherein the optical semiconductor device and the cooling device are accommodated in the hermetically sealed enclosure, and wherein at least a part of the frame carrying the optical system is formed of a material identical with a material forming the heat sink. Thereby, the part forms an integral, continuous extension of the heat sink.
