Modeling of optical aberration correction using a liquid crystal device
* [email protected], Tel: (330) 672-2511 ABSTRACT Gruneisen , has shown that small, light weight, liquid crystal based devices can correct for the optical distortion caused by an imperfect primary mirror in a telescope and has discussed the efficiency of this correction. In this paper we expand on that work and propose a semianalytical approach for quantifying the efficiency of a liquid crystal bas...
متن کاملOptical phase modulation using a hybrid carbon nanotube-liquid-crystal nanophotonic device.
The carbon nanotube-liquid-crystal (CNT-LC) nanophotonic device is a class of device based on the hybrid combination of a sparse array of multiwall carbon nanotube electrodes grown on a silicon surface in a liquid-crystal cell. The multiwall carbon nanotubes act as individual electrode sites that spawn an electric-field profile, dictating the refractive index profile within the liquid crystal a...
متن کاملGraphene-based liquid crystal device.
Graphene is only one atom thick, optically transparent, chemically inert, and an excellent conductor. These properties seem to make this material an excellent candidate for applications in various photonic devices that require conducting but transparent thin films. In this letter, we demonstrate liquid crystal devices with electrodes made of graphene that show excellent performance with a high ...
متن کاملLiquid-Crystal Optical Switches
The optical switching times of liquid-crystal cells using 5CB, 5OCB and PCH5 liquid crystal materials have been characterized as a function of applied voltage, V, and temperature, T. The transition time from 90 to 10 % transmission scales as V and is limited to 50 to 30 ns by the breakdown electric field, ~ 10 V cm of the liquid crystal. The time from the initial voltage step to 90 % transmissi...
متن کاملLiquid Crystal Optical Phase Modulators for Beam Steering
Beamsteering using liquid crystals can be achieved with refractive or diffractive implementations. The common thread in these various structures is that the liquid crystal is employed as an optical phase modulator. Either nematic or smectic liquid crystal phases can be used to shift the phase of light and steer an optical beam. Various liquid crystal optical phase modulating schemes will be des...
