Abstract
PURPOSE:To readily form the optical guide without producing any cracks by forming the grooves of the specified patterns on a glass substrate then placing the granular guartz glass material of the specified refractive index in said grooves and making the same to molten glass. CONSTITUTION:Acid-resistant resist 2 is coated on a glass substrate 1, and a speicified mask is formed thereon. Next, desired patterns are formed on the glass substrate through said mask, after which the acid-resistant resist 2 is removed. Thence, granular, preferably spherical quartz glass materials 3 having the refractive index higher than that of the substrate 1 are placed in the grooves formed to the desired patterns, after which the glass substrate 1 is heated to melt the glass materials 3, whereby an optical waveguide 4 is formed and the optical branching and coupling device is obtained. After the molting, the top surface of the glass substrate is polished, and if necessary, the film 5 of the same quality as that of the glass substrate is put on the top of the substrate.
