Abstract
A light-emitting element mount () is fixed onto a base (), and a semiconductor laser element () is fixed onto the light-emitting element mount (). An anchor member (), which is in the shape of a roughly rectangular plate, is fixed onto the base (). An optical fiber () is fixed onto the anchor member () by means of an anchoring material (). The optical fiber () is aligned and optically coupled with the semiconductor laser element (). A cut-out () is formed in the part of the base () corresponding to the anchoring material () (below the anchoring material ()). Thus the anchor member () is fixed onto the base () so as to straddle the cut-out (). Since the cut-out () is formed below the anchor member (), a spot heater () or like can be used to heat the anchor member () from the bottom surface thereof. Thus, the anchoring material () on top of the anchor member () can be efficiently heated.
