ABSTRACT:
A different wavelength type of optical source module which generates light beams different in wavelength. In the optical source module, laser diodes are provided to be opposed to each of reflective films which is arranged to make a shape of a mountain. These respective laser diodes generates laser light beams different in wavelength. The light beams generated at the laser diodes are reflected by the reflective films at a right angle to progress along the same path.
