High-Efficiency, Liquid-Crystal-Based, Controllable Diffraction Grating
Journal of the Optical Society of America A-Optics Image Science and Vision (2005)
We propose a new reflective liquid-crystal diffraction grating design attained by combining the use of a polymer wall to reduce ...
Finite-Difference Time-Domain Calculations of a Liquid-Crystal-Based Switchable Bragg Grating
Chemical Physics Publications (2004)
A polymer-wall-confined transmissive switchable liquid crystal grating is proposed and investigated by two-dimensional finite-difference time-domain optical calculation and liquid-crystal-director calculation, ...
Light Propagation in Variable-Refractive-Index Materials With Liquid-Crystal-Infiltrated Microcavities
Chemical Physics Publications (2003)
A liquid-crystal-infiltrated microcavity structure is proposed as a variable-refractive-index material. It has the advantages over previously considered nanostructured materials of ...
Multispectrum, Spatially Addressable Polarization Interference Filter
Journal of the Optical Society of America A-Optics Image Science and Vision (2002)
We review current synthesis techniques for generating and improving birefringent filters. The relationship between wave-plate orientation and the resulting spectral ...
