1. A production method for an optical component having a grating structure, comprising the steps of:
radiating non-interfering monochromatic light of an ultraviolet wavelength region onto a silica-based optical waveguide diffused with at least one of hydrogen and deuterium so as to change a refractive index of said silica-based optical waveguide; and
radiating interfering light onto said silica-based optical waveguide,
wherein said non-interfering monochromatic light is incoherent light.
