We report a low‐voltage and fast‐response polymer network liquid crystal (PNLC) infrared phase modulator. By optimizing the UV curing temperature and LC host, we achieved V2ϰ= 22.8V at λ=1.55μm and response time about 1ms. Such a PNLC‐based spatial light modulator is useful for adaptive optics, adaptive lens, and laser beam steering.
