Mid-infrared volume phase gratings manufactured using ultrafast laser inscription [PDF]
We report on the ultrafast laser inscription (ULI) of volume phase gratings inside gallium lanthanum sulphide (GLS) chalcogenide glass substrates. The effect of laser pulse energy and grating thickness on the dispersive properties of the gratings is ...

Band-edge-induced Bragg diffraction in two-dimensional photonic crystals [PDF]
Two-dimensional photonic crystals composed of two orthogonal volume diffraction gratings have been photogenerated in photopolymers. When the read beam is set at the Bragg angle, the diffraction efficiency of the transmission grating is strongly enhanced ...
