Abstract:

The report starts from the optical characterization of the photoresponsive liquid crystals LCs consisting of newly synthesized azobenzene molecules dispersed in nematic LCs. The report also contains the new finding of the optically switchable fluorescent properties of studied azobenzene molecules alone and in the azobenzene-impregnated porous silicon. Finally The PI describes his recent work on using those photoresponsive LC in two-dimensional 2D gratings and subwavelength gratings which have potential use in spectroscopic applications.
