Abstract
The photorefractive polymer dispersed liquid crystals (PDLCs) doped with the liquid crystal TL202 is studied. In samples with composition PMMA:TL202:ECZ:TNFDM, an external diffraction efficiency of 55% at 633 nm in 53-μm-thick samples at an applied field of 20 V/μm for a grating spacing of 3 μm is achieved. In 105-μm-thick samples of the same mixture, the diffraction efficiency exhibits a first maximum at an applied field of 8 V/μm and for a grating spacing of 3 μm. At an applied field of 8 V/μm, these new materials have a dynamic range that is >50 times higher than in DMNPAA:PVK:ECZ:TNF polymers.
