Abstract
AbstractA fast‐switching and scattering‐free phase modulator using polymer network liquid crystal (PNLC) is demonstrated at λ =1.55 μm for laser beam steering application. The strong polymer network anchoring greatly reduces the visco‐elastic coefficient of the LC. As a result, the PNLC response time is improved by ∼300X, although the threshold voltage is increased by ∼25X. Computer simulation results agree with experiments well.
