Abstract:
A method of manufacturing an optical semiconductor module which comprises: a base; a semiconductor laser device on the base, for emitting semiconductor laser light; and an optical fiber for transmitting the laser light emitted by the semiconductor laser device therethrough, the method comprising the steps of:forming a concave groove and an alignment mark in the base by the same etching process on the base;aligning a position of the semiconductor laser device with a position of the base using the alignment mark, and thereafter securing the semiconductor laser device to the base; andinstalling the optical fiber in the concave groove of the base;wherein the base further includes a cut recess extending in a direction vertical to an optical axis direction, andthe alignment mark comprises a base edge alignment mark formed on an edge portion of the wall of the cut recess of the base, the wall being closer to the semiconductor laser device.
