Abstract
The present invention relates to a light emitting device module which can easily be made and can yield a stable output characteristic, and a method of making the same. The light emitting device module in according to the present invention comprises a semiconductor device in which an active region having a light exit facet and a light reflecting facet with a lower light reflectivity than the light exit facet respectively at both ends is fabricated along a predetermined reference axis, and an optical fiber having a grating provided along the longitudinal direction of the core region and an end facet arranged so as to face the light exit facet. In particular, in the light emitting device module according to the present invention, the light exit facet of the active region is inclined with respect to the light reflecting facet of the active region by a predetermined angle, thereby the light reflecting facet of the active region and the grating constitute an external cavity through the light exit facet.
