Abstract
An electron definable glass or an electron sensitive glass for microstructures is provided with microstructures and optical waveguides formed therein. The microstructures are formed by electron beam irradiation in selected areas in the electron definable glass followed by a high temperature heat treatment and chemical etching, whereas the optical waveguides are formed by irradiating the electron definable glass by an electron beam followed by a low temperature heat treatment.
