2013 journal article
Multi-twist retarders: broadband retardation control using self-aligning reactive liquid crystal layers
OPTICS EXPRESS, 21(1), 404–420.
TL;DR:
This work employs a numerical design method and focuses on achromatic quarter- and half-wave MTRs, which offer remarkably effective control of broadband polarization transformation and can easily achieve large bandwidth and/or low-variation of retardation within visible through infrared wavelengths.

Efficient and monolithic polarization conversion system based on a polarization grating
APPLIED OPTICS, 51(20), 4852–4857.
TL;DR:
A new polarization conversion system based on a liquid-crystal polarization grating and louvered wave plate that manifests nearly 90% conversion efficiency of unpolarized to polarized for ±11° input light divergence, leading to an energy efficient picoprojector that presents high efficacy with good color uniformity.

2007 journal article
Elastic continuum analysis of the liquid crystal polarization grating
PHYSICAL REVIEW E, 76(2).
TL;DR:
It is shown that flow effects likely play an essential role in the fall times, presumably due to the prominent splay-bend deformation of the zero-field configuration, and the approximation technique used is likely broadly useful for many problems which include nano- or micropatterned surfaces.
