SEMICONDUCTOR LASER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a wavelength multiplex light source in a small size at a low cost and a wavelength multiplex optical module using the same.SOLUTION: Light with different wavelengths is produced by a plurality of light production parts. The light produced by each of the plurality of light production parts is reflected off a monolithic integrated mirror 9 and is made incident on a light-condensing lens. An output position on the light-condensing lens of the light produced by each of the light production parts is deviated by a predetermined amount from a central position of the light-condensing lens.
