Abstract: PURPOSE:To enable a semiconductor device to emit a circular light beam and to be improved in coupling efficiency by a method wherein a light trapping layer specified in composition is provided, and the refractive index of the layer concerned is set smaller than that of an optical waveguide by 0.5-10%. CONSTITUTION:Light trapping layers 21-24 are formed of GaxIn1-xAsyP1-y, and the refractive index of the layers concerned is set smaller than that of an optical waveguide by 0.5-10%, where x and y are so set as to satisfy formulas, 0<=x and y<=1.

By this setup, an FFP element which can emit a light beam circular in cross section and is excellent in coupling efficiency can be obtained.
