Metal holder, optical component composite body and manufacturing method

摘要

An optical component composite body is obtained in which there is no damage to the optical component even when it is bonded to a metal holder by solder or low melting point glass. The metal holder of the present invention is provided with a mounting portion protruding from one side of the main body and a grasping portion protruding from the other side of the main body. The mounting portion is provided with a plurality of protrusions formed in a comb tooth configuration. An optical component formed from alumina (Al₂O₃) is bonded by solder to a bonding surface of a protrusion, another optical component formed from LiNbO₃ is bonded by solder to a bonding surface of another protrusion, and a further optical component formed from YVO₄ is bonded by solder to a bonding surface of a further protrusion.
