ABSTRACT:
A semiconductor laser amplifier according to this invention has an optical waveguide layer containing a p-type semiconductor layer in an n-type semiconductor substrate. On one end of the n-type semiconductor substrate, for example, a reflective film is formed as light-reflecting means. In this invention, two optical waveguide layers are arranged so as to form a V with these two layers meeting each other at one end, on which the reflective film is formed, of the substrate.
