摘要： A method and apparatus for positioning a laser diode with respect to a coupling optic for a waveguide to obtain the optimum light transmission characterized by providing a reflecting reference plane or surface extending perpendicular to the axis of the waveguide adjacent the coupling optic, projecting light through the waveguide and coupling optic onto the reflecting surface, measuring the amount of light reflected into the waveguide and adjusting the axial position of the waveguide and optic relative to the reflecting surface to obtain the optimum value, then placing the semiconductor with the facet in the reference plane and either operating the semiconductor to provide light for coupling into the waveguide and adjusting the relative positions in a transverse plane to the axis of the waveguide to obtain the optimum transmission or operating the semiconductor laser as a detector and coupling light into the waveguide at a point spaced from the laser to project into the detector and making adjustments in the transverse direction to obtain the optimum reading. The reflecting surface can be either a separate reflecting device or the facet of the laser. The apparatus includes two members each having an abutting surface with one of the members positioning the waveguide with the coupling optic to lie along an axis perpendicular to the abutting surface and the other member positioning the semiconductor laser with the facet lying in the plane of the abutting surface.

摘要： An external optical resonator for a semiconductor laser is composed of an optical directional coupler which can be formed as an integrated optical coupler with a short structural length that enables a free spectral range in the order of 100 GHz and enables the resonator and the system fiber to be coupled to the same end face of the laser. The resonator structure includes two optical waveguides with feedback means applied on the end faces of one of the waveguides and the other waveguide having one end face coupled to receive the output of the laser and the other end face of the other waveguide being coupled to the system fiber. The arrangement is particularly useful for tunable semiconductor lasers, particularly for heterodyne reception.
