OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2018/180807
Kind Code:
A1
Abstract:
The present invention comprises: a plurality of laser diodes (11) which are light-emitting elements; a plurality of mirrors (13), each having a reflective surface (13r) that reflects the light emitted from the laser diodes (11); and a sub-mount (4) having a plurality of the laser diodes (11) disposed on one surface thereof. A portion of the plurality of mirrors (13) are disposed at a position which overlaps the reflected light reflected by the other mirrors (13) in plan view of the one surface of the sub-mount (4), and each mirror of this portion of the mirrors (13) has a fixed surface (13f) that is fixed to the sub-mount (4) with an adhesive. The fixed surface (13f) is perpendicular to the reflective surface (13r), and the fixed surface (13f) and a fixing surface (40) of the sub-mount (4) to which the fixed surface (13f) is fixed are non-perpendicular to the direction in which the portion of mirrors (13) overlaps the reflected light.
