ABSTRACT:
BACKGROUND OF THE INVENTION
Semiconductor modules generally have a form in which a distal end of an optical fiber and a semiconductor laser chip are optically connected with each other and are accommodated in a package, for example. The package of such semiconductor laser modules is made of a metal, for example, and a Peltier module is disposed in many cases inside the package to regulate the temperature of the semiconductor laser chip.
SUMMARY OF THE INVENTION
According to one aspect of the present invention, there is provided a semiconductor laser module that comprises an optical fiber, a semiconductor laser chip optically coupled with a distal end of the optical fiber, a box-shaped package for accommodating therein the semiconductor laser chip under an optical coupling state with the distal end of the optical fiber, and a Peltier module fixed to a bottom plate of the package, for regulating the temperature of the semiconductor laser chip, wherein the bottom plate of the package is made of a metal, and at least a peripheral wall portion of the package is made of a resin or a ceramic.
According to another aspect of the present invention, there is provided a semiconductor laser module that comprises an optical fiber, a semiconductor laser chip optically coupled with a distal end of the optical fiber, a box-shaped package for accommodating therein the semiconductor laser chip under an optical coupling state with the distal end of the optical fiber, and a Peltier module disposed inside the package, for regulating a temperature of the semiconductor laser chip, wherein at least a bottom portion and a peripheral wall portion of the package are made of a resin or a ceramic, and an opening is formed in the bottom portion of the package; and wherein the Peltier module is disposed inside the package while the bottom surface thereof is exposed from the opening of the package.
