Abstract:
An optical integrated unit comprising:a substrate; and a semiconductor laser element mounted on a main surface of said substrate; wherein: said semiconductor laser element has a configuration such that a first laser excitation portion for emitting a first laser beam of a first wavelength and a second laser excitation portion for emitting a second laser beam of a second wavelength that differs from said first wavelength are integrated in a monolithic manner, and also said first laser beam and said second laser beam are emitted in a substantially parallel direction with respect to said main surface of said substrate; and said substrate includes: a mirror surface inclined with respect to said main surface in such a manner that said first and second laser beams are reflected substantially perpendicularly upward with respect to said main surface; and means for providing electrical separation between a first mount portion corresponding to said first laser excitation portion and a second mount portion corresponding to said second laser excitation portion.
