Wilkinson Electrically Switchable Diffraction Grating Using a Hybrid Liquid Crystal and Carbon Nanotube-Based Nanophotonic Device Advanced Optical Materials 1
A hybrid liquid crystal and carbon nanotube-based device which shows the capacity to perform as a switchable diffraction grating is demonstrated. A liquid crystal layer is sandwiched between two patterned electrodes, the first comprising a 2D array of carbon nanotubes and the second comprising an ITO-based in-plane switching electrode on glass. The device displays quite distinct voltage-dependent diffraction patterns due to the two different electrodes.
