Abstract
We demonstrate a switchable hybrid grating lens array using a nanophotonic device fabricated from multiwall carbon nanotubes and liquid crystals which combines diffraction, lensing, and dispersion. Diffraction experiments and computer simulations both show clear and well defined diffraction orders in two dimensions with voltage dependent diffraction efficiency. These characteristics enable the device to be used in the fabrication of miniaturized spectrometers and integrated optics. © 2010 American Institute of Physics.
