摘要:
An optical element-optical fiber composite structure having a high resistance of the optical fiber to breakage due to cyclical change in temperature, includes a package structure having a main container (23), side containers (27) attached to the main container (23) and sleeves (25) through which a main chamber (22) of the main container (23) is connected to side chambers (28) of the side containers (27); an optical element (21) housed in the main chamber (22); and optical fibers (29) introduced into the main chamber (22) through the side chambers (28) and the sleeves (25) and connected to the optical element (21).
