ABSTRACT:
An optical device comprises a light emitting device for emitting a light beam whose radiation angle is less than 15 degree and having a light emitting end surface on which a antireflection layer is formed, an optical fiber having a flat light incident end surface on which a antireflection layer is formed and a diffraction grating formed therein, and a substrate for supporting the light emitting device and the optical fiber so as to oppose the antireflection layer of the light emitting device to the antireflection layer of the optical fiber.
