Submillisecond-response polymer network liquid crystal phase modulators at 1.06- μ m wavelength

A fast-response and scattering-free polymer network liquid crystal (PNLC) light modulator is demonstrated at λ=1.06 μ m wavelength. A decay time of 117 μ s for 2π phase modulation is obtained at 70°C, which is ∼650×faster than that of the host nematic LCs. The major tradeoff is the increased operati...

Description
Summary:A fast-response and scattering-free polymer network liquid crystal (PNLC) light modulator is demonstrated at λ=1.06 μ m wavelength. A decay time of 117 μ s for 2π phase modulation is obtained at 70°C, which is ∼650×faster than that of the host nematic LCs. The major tradeoff is the increased operating voltage. Potential applications include spatial light modulators and adaptive optics.
