TLDR
It is demonstrated that the LCs or LC mixtures with higher nematic-isotropic phase transition temperatures have higher optimum temperatures and greater potential for improving the figure of merit.Abstract:
This paper describes analyses and confirming experiments on the optimum temperature for fast response in nematic liquid crystal (LC) modulators. It is demonstrated that the LCs or LC mixtures with higher nematic-isotropic phase transition temperatures have higher optimum temperatures and greater potential for improving the figure of merit. Also discussed is the performance of the LC mixture exhibiting optimum temperature at around room temperature.read more

TL;DR: In this paper, a phase profile is imposed on an optical beam as it is either transmitted through or reflected from the phase shifter array, and the imposed phase profile steers, focuses, fans out, or corrects phase aberrations on the beam.
