Spectrally Tunable Airy Beam Generation Using Cholesteric Liquid Crystals
2018 CONFERENCE ON LASERS AND ELECTRO-OPTICS (CLEO)(2018)
摘要
We demonstrate spectrally tunable Airy beams via a chiral Bragg reflector. Specifically, we photo-align a cholesteric liquid crystal such that it conditionally imparts a cubic phase dependent on voltage applied across the sample.
