ABSTRACT:
A collimated laser beam focuses on a substrate put in a reaction vessel which includes glass raw materials to raise the temperature high enough for the thermal reaction of the glass raw materials to form a glass layer. The repeated scanning of the glass substrate with the laser beam accumulates a plurality of layers and forms an optical waveguide on the glass substrate.
