Abstract: PURPOSE:To hold a photodetecting level constant even for a variation in the wavelength of a signal light by composing a wavelength filter of a waveguide diffraction grating, and forming a carrier injection enabling structure. CONSTITUTION:In an integrated optical semiconductor element in which a plurality of photodetectors 121, 122, a wavelength filter 111, and an optical guide 101 are integrated on a semiconductor substrate 100, the filter 111 is formed of a waveguide diffraction grating, and formed in a carrier injection enabling structure.
