Metal holder, optical component composite body and manufacturing method

A metal holder to which are fixed by fusion bonding of low melting point glass or solder a plurality of optical components into which light is irradiated, wherein

• the metal holder is provided with:
• a mounting portion to which said optical components are bonded and fixed,
• protrusions so that portions of one end of a light entrance surface or light exit surface of the optical components can be bonded and fixed to said mounting portion, and
• a step portion for bonding said optical components to a surface of said protrusions.

A metal holder to which are fixed by fusion bonding of low melting point glass or solder a plurality of optical components into which light is irradiated, wherein

• the metal holder is provided with:
• a mounting portion to which said plurality of optical components are bonded and fixed,
• a plurality of protrusions that are formed in a comb tooth configuration so that portions of one end of a light entrance surface or light exit surface of the optical components can be bonded and fixed to said mounting portion, and
• a step portion for bonding said optical components to a surface of said protrusions.

An optical component composite body in which optical components into which light is irradiated are fixed by fusion bonding of low melting point glass or solder to a metal holder, wherein

• the metal holder is provided with:
• a mounting portion that constitutes protrusions protruding from a body of said metal holder, and
• a step portion for bonding said optical components to a surface of said protrusions;
• and wherein
• one end portions of a light entrance surface or light exit surface of the optical components are fixed by fusion bonding of the low melting point glass or solder to the step portion.

An optical component composite body in which a plurality of optical components into which light is irradiated are fixed by fusion bonding of low melting point glass or solder to a metal holder, wherein

• the metal holder is provided with:
• a mounting portion in which a plurality of protrusions are arranged in a comb tooth configuration, and wherein
• portions of one end of a light entrance surface or light exit surface of the optical components are fixed by fusion bonding of the low melting point glass or solder to each of the protrusions, and
• said portions of one end have a spacing between themselves and bonding surfaces of the protrusions.

A method for manufacturing an optical component composite body in which optical components into which light is irradiated are fixed by fusion bonding of low melting point glass or solder to a metal holder, comprising:

• a placing step in which a metal holder that is provided with a mounting portion in which protrusions that form step portions as bonding surfaces with portions of one end of a light entrance surface or light exit surface of the optical components are arranged is placed in a jig;
• an interposing step in which the solder or low melting point glass is interposed between the portion of one end of at least one of a light entrance surface or light exit surface of the optical components and the step portion formed on a surface of said protrusions;
• and
• a melting step in which the solder or low melting point glass is melted.

• an interposing step in which, in order that edges of portions of one end of at least one of a light entrance surface or light exit surface of the plurality of optical components are not bonded to the bonding surfaces, the low melting point glass or solder is interposed between the optical components and the protrusion in an area away from the edges;
• and
• a melting step in which the low melting point glass or solder is melted.
