Abstract

A method of producing optical waveguide gratings that includes a grating portion formation step for forming a grating portion in an optical waveguide having a core composed of a material with a refractive index that changes when exposed to UV light by irradiating the optical waveguide with a UV beam from a Uv light source. The UV
beam's exposure time of the optical waveguide is varied along the longitudinal direction of the optical waveguide during the grating portion formation step by positioning a shielding plate between the optical waveguide and the W
light source and moving the shielding plate while irradiating with the UV beam.
