More Information
Summary:A diffraction grating coupler which includes an optical waveguide having a first surface and a second surface opposing the first surface, the optical waveguide having a grating on one of its surfaces. The diffraction grating coupler further includes an elastic polymer film deposited on and attached to the optical waveguide, the elastic polymer film partially surrounding the optical waveguide and leaving one of the two surfaces of the optical waveguide open, the diffraction grating coupler being mountable on a specimen by attaching the elastic polymer film to the specimen.
