Abstract
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.
Claims14
A diffraction grating coupler which comprises an optical waveguide having a first surface and a second surface opposing to said first surface, said optical waveguide having a grating on one of said surfaces, said optical waveguide beign made of at least one hard optical material, and
- a soft polymer film deposited on and attached to said optical waveguide, said soft polymer film partially surrounding said optical waveguide and leaving one of said two surfaces of said optical waveguide open, the diffraction grating coupler being mountable on and temporally adherable to a specimen by attaching said soft polymer film to said specimen.
