A fast response and scattering free homogeneously aligned polymer network liquid crystal (PNLC) was demonstrated for infrared light modulators at λ = 1.55 μm. To reduce operating voltage, a higher birefringence and larger dielectric anisotropic liquid crystal was considered. PNLC cells were fabricated by mixing a few percent of photocurable monomer to a nematic LC host. The strong polymer network anchoring helped LC to relax back as the electric field was removed. Due to this, the PNLC response time was ∼250× faster than that of the E44 LC mixture.
