摘要： PROBLEM TO BE SOLVED: To provide an optical waveguide having no excess loss in which Ge contents of the core and of the clad matches with each other with good accuracy, and to provide its producing method. SOLUTION: The difference in the refractive index between the core region 3 and clad region 2, 4 is controlled to a desired value by the amt. of Ti added to the core region 3. By irradiating the core region 3 and clad region 2, 4 with UV laser beam, gratings having periodical distribution of refractive indices are formed in both of the core region 3 and the clad region 2, 4 where the optical signals are diffused, and the excess loss due to the clad mode can be suppressed. By using SiO2 targets 8-1 to 8-4 containing Ge of a same compsn. for the formation of the core region 3 and clad region 2, 4, the Ge contents of the core region 3 and of the clad region 2, 4 can be controlled to match with each other with high accuracy.

摘要： PROBLEM TO BE SOLVED: To provide a method for dry etching capable of vertically etching a wall surface with smooth surface and wall surface by optimally setting the thickness of a CFx polymer film adhered to the etching wall surface. SOLUTION: A lower electrode 6 is cooled and held by feeding ethylene glycol at 40 to 200 deg.C to a liquid circulating path 21. The electrode 6 is cooled, and hence He in an He circulating part 14 is cooled, and the rear surface of a sample 12 in contact with He is cooled. The temperature of the rear surface of a sample 12 can be set higher as compared with the case that the rear surface of the sample 12 is cooled via the He and the temperature of the rear surface of the sample 12 can be set lower as compared with the case that it is cooled with water. The ethylene glycol at 40 to 200 deg.C is used instead of the water flowing to the path 21 to obtain the optimum temperature of the rear surface of the sample 12. Chemical etching by radical can be sufficiently suppressed, and smooth etching wall surface is obtained with excellent verticality.
