| titleOfInvention | Phase mask for manufacturing diffraction grating and method for manufacturing the same |
| abstract | Abstract: PROBLEM TO BE SOLVED: To provide a phase mask for producing a diffraction grating in which the zero-order light component transmitted without being diffracted is made as small as possible so that noise is not generated in the reflection spectrum of the transferred optical waveguide diffraction grating and the phase mask. Manufacturing method of such a phase mask. SOLUTION: A repetitive pattern of a lattice-like concave groove and a convex stripe is provided on one surface of a transparent substrate 2, and the phase mask 1 forms a diffraction grating by interference fringes of diffracted light by the repetitive pattern. A phase mask for producing a diffraction grating, wherein a cross-sectional shape of a repetitive pattern of convex stripes is formed in a substantially sinusoidal shape. |
