Abstract: PURPOSE: A method for fabricating planar optical waveguide element using optical sensitivity is provided to enhance the efficiency in a light transmission process by simplifying a process for forming a waveguide layer. CONSTITUTION: A lower clad layer(200) is formed on an upper face of a silicon substrate(100) or a silica substrate or an alumina substrate. A core layer(400) including Ge or Ge, Er, Yb, and Nb is formed on an upper face of the lower clad layer(200). An upper clad layer(500) is formed on an upper face of the core layer(400). A hydrogen process for a waveguide stacked layer including the upper clad layer(500) is performed to increase the optical sensitivity between Ge and ultra-violet ray. A photo mask(600) is deposited on an upper face of the upper clad layer(500). An optical waveguide(401) is formed by irradiating the ultra-violet laser beam thereon.
