    摘要: An optical element mounting substrate where a plurality of light emitting elements have been mounted on the same plane, a lens array for collimating a plurality of light emitted from the plurality of light emitting elements, and a wavelength multiplexing/demultiplexing device are prepared. The wavelength multiplexing/demultiplexing device has typically mounted both a wavelength selecting filter and a mirror on front and rear planes of a transparent substrate. These three components are mounted within a package at a desirable angle position. Optical axes of respective wavelengths of the wavelength multiplexing/demultiplexing device are determined based upon a thickness and an angle of the light emitting element mounting substrate, and are arrayed on a straight line of a horizontal plane. As a consequence, if the respective light emitting elements are arranged on the optical axes which are exclusively determined by a design work, then optical multiplexing/demultiplexing operations can be carried out.

    摘要: A semiconductor laser device is provided which is designed to prevent end surface optical damage, thereby permitting an increase in the output of the semiconductor laser. To achieve this, an active layer at the light emitting end surface portion of the semiconductor laser device is recessed inwardly by a distance between 50 nm and 300 nm (depending on the amount of etching) from the end surfaces of the crystal layers lying on both sides of the active layer. The recess serves to improve the heat dissipation of the active layer portion. This results in improving the amount of light output of the semiconductor laser which is possible without causing optical damage. A method for making the device is also provided. This method permits achieving the above-noted advantages simply by adding an etching step to the conventional semiconductor laser fabrication process, without requiring special equipment or technique.
