Fast-response infrared phase modulator based on polymer network liquid crystal
We report a high birefringence terphenyl liquid crystal mixture, designated as M3, for infrared phase modulation with special emphasis on mid-wave infrared (MWIR). In addition to high birefringence, M3 exhibits excellent UV stability, modest dielectric anisotropy, and a very broad nematic range. The high birefringence enables a thin cell gap to be used for achieving a 2π phase change while main...
متن کاملFast-Response Infrared Ferroelectric Liquid Crystal Phase Modulators
A high speed phase modulator based on ferroelectric liquid crystal (FLC) is demonstrated. For uniform alignment and pure phase modulation, we propose a new FLC device using a short helical pitch material in a homeotropic alignment. This device is driven by periodic in-plane electrode stripes implemented on the surface of both cell substrates. As a result, we have obtained a large phase modulati...
متن کاملSubmillisecond-response and scattering-free infrared liquid crystal phase modulators.
We demonstrate a submillisecond-response and scattering-free infrared phase modulator using a polymer network liquid crystal (PNLC). The required voltage for achieving 2π phase change at λ = 1.06 µm is 70V (or 5.8 V/μm) and the measured response time is ~200 µs at 25°C and 30 µs at 70°C. Opposite to our conventional understanding, a high viscosity LC helps to achieve small domain size during po...
متن کاملHysteresis-free and submillisecond-response polymer network liquid crystal.
We demonstrate a polymer network liquid crystal (PNLC) with negligible hysteresis while keeping submillisecond response time. By doping about 1% dodecyl acrylate (C12A) into the liquid crystal/monomer precursor, both hysteresis and residual birefringence are almost completely eliminated. The operating voltage and scattering properties remain nearly intact, but the tradeoff is enhanced double re...
متن کاملSubmillisecond response variable optical attenuator based on sheared polymer network liquid crystal.
We demonstrate a variable optical attenuator (VOA) at lambda=1.55 microm using a sheared polymer network liquid crystal (SPNLC). The SPNLC exhibits a fast response time and weak wavelength dependency. Comparing with other polymer-stabilized liquid crystals, the SPNLC has lower driving voltage and negligible light scattering loss when the wavelength exceeds 700 nm. A reflection type VOA with ~0....
