a large amount of boron added in the silica thin film, and also the evaluation of the double refraction and the thought method

摘要

this invention is related to optical communication and optical industry used silicon to judging the boron, (p), germanium (Ge), titanium (Ti). the film's name is also the element and a double refraction occurs as a new kind of method to reduce the uc704ud55c be about to according to the invention, the flame hydrolysis method for coating thin film of silica production in the process of the film or in the buffer, the core and the primary layer of each layer. a large amount of boron is added to the method, the thermal expansion rate of the silica layer a lot of. as the liquid in the high transition temperature as low as a line dance, double refraction to have purpose, flame hydrolysis reaction in the coating of the particle layer to melt the film culture and to make the fire warm blooded and the amount of boron. in the box. in short, the stability of a silica thin film with high quality in order to make the invention.
