  • Spatial light modulator incorporating aberration correction
    Patent number: 11940686
    Abstract: A spatial light modulator (100) comprises a liquid crystal material (104), first and second electrodes (106, 108) disposed on opposing sides of the liquid crystal material (104), and a diffractive optical element (120) disposed between the electrodes (106, 108) and extending laterally across the modulator (100). The diffractive optical element (120) comprises an array of diffracting formations (122) formed from sub-wavelength structures. The array of diffracting formations (122) defines a phase profile adapted to modify the incident wavefront of light reflected off the second electrode and to apply a position-dependent wavefront correction to the incident wavefront of light.

  • Tunable optical supercontinuum enhancement
    Patent number: 8718411
    Abstract: A method and apparatus for providing optical supercontinuum. The method comprises creating a spectrally narrow phase feature within a supercontinuum spectrum produced from a laser pulse that has been subjected to supercontinuum generation, thereby producing a modified supercontinuum spectrum, and propagating the modified supercontinuum spectrum through an optical waveguide that is suitable for supercontinuum generation, thereby further modifying the modified supercontinuum spectrum. The method may include modifying the modified supercontinuum spectrum by increasing its energy in a vicinity of the phase feature.
