Patent DE-19544125-A1 (DE)
Inventor: EDLINGER JOHANNES
IPC: B23K26/06
Filed: 1995-11-27
Abstract: A diffraction grating structure for coupling light into or out of a high refractive index waveguide layer 2 on a carrier substrate 1 is formed by irradiating the carrier substrate 1 and/or the layer 2 with UV laser light that is subject to simultaneous, spatially periodic intensity modulation. The modulation may be achieved, for example, by means of a biprism 18, two UV laser beams interfering (Fig. 5) or a mask (20, Fig. 7). The modulated UV light has the effect of periodically modulating the local refractive index of the waveguide layer or of the surface of the substrate to form the diffraction grating. The layer thickness of the waveguide layer or the substrate surface or a sacrificial layer, may be modulated by ablation by the laser light. The dielectric layer may contain TiO2, Ta2O5, HfO2, Al2O3, Nb2O5, Y2O3, ZrO2, or nitrides or oxynitrides of Al, Si or Hf. <IMAGE>
