Multi-twist retarders: broadband retardation control using self-aligning reactive liquid crystal layers

OPTICS EXPRESS, 21(1), 404–420.

By: R. Komanduri n, K. Lawler n & M. Escuti n 

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.

By: J. Kim n, R. Komanduri n, K. Lawler n, D. Kekas & M. Escuti n 

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.
