  • Process for forming an optical waveguide
    Patent number: 4100313
    Abstract: A technique for generating long narrow microstructures based upon the shadowing effect of thick slits placed between a source and a substrate. The method is particularly well suited for forming optical waveguides using a mask having a slit with a width larger than the width of the stripe to be deposited and being thick relative to the width of said slit.

  • Optical coupler having improved efficiency
    Patent number: 4097117
    Abstract: The optical efficiency, with which a coupling portion of a fiber-optic can be coupled by evanescent fields to a planar optical waveguide through a phase-matching diffraction grating on the surface of the planar optical waveguide, is increased by deforming the coupling portion so that it is a negative replica of the undulating surface of the diffraction grating.
