Abstract
Disclosed are an optical device capable of precise adjustment of optical output intensity, and a method for manufacturing an optical device. An optical device including a laser diode, according to one aspect of the present embodiment, comprises: a laser diode for outputting light having a predetermined wavelength; an optical output unit in which output light of the laser diode is optically coupled and the output of the optical device takes place; and an optical isolator disposed between the laser diode and the optical output unit. The output light of the laser diode passes through the optical isolator and the output of the optical device takes place through the optical output unit, and the intensity of the output light of the optical device is determined by the rotation of the optical isolator.
