Abstract
PURPOSE: To make it possible to produce a dielectric diffraction grating of high quality massively at a low price by piling a plurality of glass materials having different refractive indexes alternately upon the inner wall of a tubular starting member and by cutting the mother material into a planar shape.
CONSTITUTION: A glass layer 21 of low refractive index and a glass layer 22 of high refractive index are laminated laternaly upon the inner wall of a quartz tube 20 as a mother member by a CVD method. The mother material 2 for the dielectric diffraction grating obtained is cut in the radial direction along line CC' into a planar shape. The mother material 2 thus cut is heated and oriented such that its spacing of the frating takes a preset value and then is cut to a preset size to produce a dielectric diffraction grating 1.
