Abstract
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.
