Abstract

PURPOSE:To manufacture an efficient switch of simple constitution easily by obtaining a matrix-shaped optical waveguide by recrystallizing the surface part of a glass substrate of specific composition containing Pb and Ge, and arranging a cross-finger electrode on each branch part surface. CONSTITUTION:On the surface part of a glass substrate 101 of composition shown by formulaIor II (0<x<=1), recrystallized layers 102-104, and 105-107 are formed and on the cross branch part surfaces, cross electrodes 111-119 are arranged. Each recrystallized layer may have optional thickness by adjusting, for example, the intensity, irradiation time, etc., of work laser beam, so an efficient optical switch having good reproducibility is obtained. For example, beam incident to an optical waveguide 102 travels straight normally and is absorbed by the bud 120 of the other end part. As an electric field is applied to the cross finger electrodes 111, a Bragg diffraction phenomenon occurs, and the electric field enters the optical waveguides 105, whose output is supplied to an ADP, etc., thus performing switching operation.
