OPTICAL COMPONENT AND METHOD FOR MANUFACTURING THE SAME

摘要

Glass comprising at least one material, as a heat source material for absorbing and converting a laser beam to heat, selected from Ni, Fe, V, Cu, Cr, and Mn and added to a glass matrix comprising at least one glass forming oxide selected from SiO₂, GeO₂, B₂O₃, P₂O₅, TeO₂, Ga₂O₃, V₂O₅, MoO₃, and WO₃ and at least one material selected from alkali metals, alkaline earth metals, rare earth elements, and transition elements is provided. A laser beam with a wavelength capable of absorbing the heat source material is applied to the surface and/or inside of the glass to convert the exposed part to a single crystal or a group of crystal grains free from the heat source material and comprising components contained in the glass matrix and thus to form a pattern. Thus, an optical component having excellent secondary optical nonlinear properties is obtained.
