ド結合装置。 In a laser diode coupling device comprising a laser diode mounted on a stem and a lens in front of the laser diode to focus light onto an optical fiber, the lens is a spherical body disposed in a small hole in the center of a cylindrical metal cap. The lens is placed and fixed on the stem so that it can focus the light oscillated from the laser diode, while the end surface of the optical fiber is processed and polished, and after being fixed in the predetermined position of the optical connector, it is screwed into the receptacle. A laser diode coupling device characterized in that the stem and receptacle are fixed such that the fiber end and the optical axis of the laser beam from the spheroidal lens coincide.
