Abstract

PURPOSE:To form a satisfactory optical waveguide whose scattering loss is small, by a simple method, by irradiating a laser beam onto a glass substrate consisting of a specific lead - germanium compound, forming a recrystallized layer, and making this recrystallized layer an optical waveguide. CONSTITUTION:Laser beams emitted from a laser oscillation part 11 are made parallel light beams through a lens 12 and 13, are reflected by a mirror 15, are focused by a lens 14, and irradiate locally a glass substrate 17 consisting of Pb5Ge3O11 (A) or Pb5Ge3-XSiXO 11(0<X<=1) (B) placed on a work table 16. The part irradiated by the laser beams is recrystallized. The recrystallized A or B is transparent and also its refractive index is larger than that of the A or B glass part of the substrate, therefore, it can be used as an optical waveguide. In this regard, the refractive index is varied continuously in the boundary part of this optical waveguide and glass. As a result, an optical waveguide whose scattering loss is small is formed.
