Abstract
A method for manufacturing a blazed diffraction grating made of a crystalline material comprising gallium phosphide (GaP) or gallium arsenide (GaAs) includes forming the blazed diffraction grating by forming a plurality of grating grooves on a machined surface of a workpiece by machining, wherein the grating grooves are formed so that a surface comprising a (110) plane is arranged to receive the most incident light among the surfaces that constitute each grating, where (110) describes a crystal orientation of the crystalline material.
