Optical member holding device, semiconductor laser device, method of manufacturing optical member holding device, and method of manufacturing semiconductor laser device

An optical member holding device comprising:

• a holding member having a recess defined by one or more lateral surfaces and a bottom surface with a through-hole opening at the bottom surface of the recess;
• an optical member disposed on the bottom surface of the recess, and including a light transmissive part configured to allow at least a portion of light that enters the through-hole of the holding member to pass through, the optical member having an upper surface and one or more lateral surfaces;
• and
• an elastic member consisting of an inorganic material, the elastic member having a wavelike shape in a plan view and disposed between the one or more lateral surfaces of the recess and the one or more lateral surfaces of the optical member so as to be in contact with the one or more lateral surfaces of the recess and the one or more lateral surfaces of the optical member to exert elastic force that secures the optical member to a predetermined location in the recess.
