Abstract

PURPOSE: To make it possible to cover a wide wavelength region with one grating, by changing the depth from the mountain part to the valley part of a groove, which is formed on the surface, according to a prescribed function for the vertical direction of the groove.
CONSTITUTION: The light from laser light source 1 is irradiated onto photoresistor 9 on the surface of grating substrate 8 through lens systems 2 and 3, lens 5, translucent mirror 6, reflective mirror 7, and so on so that both light fluxes may overlap. If mask 11 is moved under a prescribed control, a groove of the depth changed according to a prescribed function along the vertical direction of the groove can be obtained. In respect to the diffraction efficiency of the grating produced in this manner, both features of the grating of a shallow groove and the grating of a deep groove are introduced to show a good diffraction efficiency throughout a wide wavelength region, so that a wide wavelength region can be covered with one grating.
