Method for fabricating laser diode having optical fiber Bragg grating as front mirror of external resonator and laser diode fabricated thereby

摘要

A method for fabricating a laser includes preparing an optical fiber including the optical fiber Bragg grating formed at a region thereof, and a ferrule provided with a cylindrical free space penetrating both ends thereof; applying a first thermal epoxy resin to a partial region of the outer cylindrical surface of the other region of the optical fiber, at which the optical fiber Bragg grating is not formed; inserting the optical fiber into the ferrule so that the region of the optical fiber at which the optical fiber Bragg grating is formed and the region of the optical fiber to which the first thermal epoxy resin is applied are located in the cylindrical free space of the ferrule; fixing the optical fiber to the ferrule by curing the first thermal epoxy resin; and optically coupling one end of the optical fiber, fixed to the ferrule, and a light source.
