  • System for coupling radiation into a waveguide
    Patent number: 10082624
    Abstract: A photonics integrated device for coupling radiation using flood illumination is disclosed. The photonic integrated device comprises an integrated waveguide, a coupler grating at the surface of the device for coupling radiation from said flood illumination towards the integrated waveguide, and a grating for blocking, reflecting or redirecting radiation away from the coupler grating at the surface of the device. The grating for blocking, reflecting or redirecting radiation away from the coupler grating thereby is positioned relative to the coupler grating so as to prevent at least some radiation from said flood illumination, impinging at the grating for blocking, reflecting or redirecting radiation away from the coupler grating and thus impinging at a position of said surface away from the coupling grating, from being reflected within the device towards the coupler grating.
