Title: Method for working optical parts
Inventor: UCHIDA TEIJI
IPC: G02B6/122
Filed: 1994-03-28
Abstract: PURPOSE:To form a groove for reflecting constituted so that loss is drastically reduced by forming it by cutting a substrate while rotating a disk-like blade consisting of a range containing diamond grains. CONSTITUTION:The disk-like blade consisting of a resin with diamond grains obtained by mixing the diamond grains in a resin material is used as the blade. By rotating the blade and cutting the optical waveguide substrate of a double ion exchange glass on which an optical waveguide is formed while an abrasive grain consisting of SiO2 and cooling solution are poured, the groove for reflecting 13 is formed. Thus, an excellent reflecting surface is obtained. Since the blade containing the diamond grains is used, it is hard, the shake thereof is not caused at a cutting time and the cuttability thereof is excellent. Besides, since the side surface of the groove obtained by cutting is polished with the small grain-size diamond brought into contact with the side surface of the blade, it becomes smooth.
