  • Polarization-insensitive optical filter which has resonant gratings and is adjustable according to the incidence angle
    Patent number: 9036967
    Abstract: The invention relates to a polarization-insensitive optical filter centered on a wavelength measured in vacuum, comprising: first and second waveguides each having a propagation mode; a first grating formed in or on the surface of the first waveguide, the first grating being periodical at least along a first axis Ox defining a first orthonormal base Oxyz; a second grating formed in or on the surface of the second waveguide, the second grating being periodical at least along a second axis Ox? defining a second orthonormal base Ox?y?z; wherein the first and second grating are provided one above another and are such that the first axis Ox and the second axis Ox? define an angle ? different from ±?/2 radians so that, when the first grating is illuminated by a light beam, the propagation modes are excited and have orthogonal fields for an angle of incidence of the light beam.

  • POLARIZATION-INSENSITIVE OPTICAL FILTER WHICH HAS RESONANT GRATINGS AND IS ADJUSTABLE ACCORDING TO THE INCIDENCE ANGLE
    Publication number: 20130301988
    Abstract: The invention relates to a polarization-insensitive optical filter centered on a wavelength (?0) measured in vacuum, comprising: first and second waveguides each having a propagation mode; a first grating formed in or on the surface of the first waveguide, the first grating being periodical at least along a first axis Ox defining a first orthonormal base Oxyz; a second grating formed in or on the surface of the second waveguide, the second grating being periodical at least along a second axis Oxy? defining a second orthonormal base Ox?y?z; wherein the first and second grating are provided above each other and are such that the first axis Ox and the second axis Ox? define an angle ? different from ±?/2 radians so that, when the first grating is illuminated by a light beam, the first and second propagation modes are excited and have orthogonal fields for a predetermined angle of incidence of the light beam.
