Abstract
Dual-period tunable phase grating using polymer stabilized blue phase liquid crystal is demonstrated by controlling its driving scheme. High efficiencies of 35.3% for the small-period phase grating and 28.7% for the large-period phase grating have been achieved because of the rectangular-like phase profile which shows good agreement with the simulation results. The diffraction angle can be alternatively tuned, as well as the diffraction efficiency. Moreover, this device also possesses polarization independency and fast response with a rise time of 826 μs and a decay time of 1.143 ms which shows great potential for diffractive optics.
