Abstract
PURPOSE: To enable the diffraction grating having the grooves of nearly desired shapes to be created by cutting and polishing the multilayer films laminated with the specific dielectric films in the film thickness direction then etching the polished surfaces.
CONSTITUTION: SiO2 and B2O3 are simultaneously evaporated toward a glass substrate 4 from vapor sources 5, 6 in a vacuum vessel, whereby SiO2-B2O3 glass is formed on the substrate 4. At this time the composition of the glass is so controlled as to become the concentrations shown in the figure, thus the galss films 7 of 1000 or more layers whose concentrations change periodically are formed. Next, the substrate 4 is withdrawn from the vacuum system and is cut and polished in the direction perpendicular to the films 7. Thereafter, the substrate 4 with its polished surface 10 being faced downward is dipped in the hydrofluoric acid of the etching solution, whereby the surface 10 is etched according to the concentrations of the composition B2O3 which is easy to be etched. As a result, the diffraction grating formed with the grooves 11 having the saw tooth form section as illustrated is obtained.
