Liquid Crystal on VLSI Silicon Optical Phased Array
Several applications for solid-state, random access beam directors have emerged in recent years, including scanners, laser radar components, interconnects, elements for addressing holographic storage, beam routing devices, and adaptive switching networks. We discuss implementation of optical phased arrays using a liquid crystal on silicon approach. By using very large scale integration (VLSI) t...
متن کاملOptical correlation by use of partial phase-only modulation with VGA liquid-crystal displays.
The development of liquid-crystal panels for use in commercial equipment has been aimed at improving the pixel resolution and the display efficiency. These improvements have led to a reduction in the thickness of such devices, among other outcomes, that involves a loss in phase modulation. We propose a modification of the classical phase-only filter to permit displays in VGA liquid-crystal pane...
متن کاملAdvanced Liquid Crystal on Silicon Optical Phased Arrays
Non-mechanical beamsteering eliminates the need for massive optomechanical components to steer the field of view of optical systems. This benefit is to come in the form of compact, low-power, lightweight optical phased arrays (OPAs) that provide better control with greater flexibility in their steering capability than their mechanical counterparts. Due to such benefits, there is a need to devel...
متن کاملSilicon oxide deposition for enhanced optical switching in polydimethylsiloxane-liquid crystal hybrids.
We report an optical switch based on a diffraction grating by combining PDMS microstructures with a photo-responsive Nematic Liquid Crystal (NLC). The grating was realized via replica molding and was subsequently coated with a thin SiO layer. SiO induced a full planar alignment of the liquid crystal. The induced parallel alignment of the LC reduces the response time of the structure by approxim...
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...
