摘要

We demonstrate a variable optical attenuator (VOA) at λ = 1.55μ musing 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 700nm. A reflection type VOA with ∼0.24ms response time and-32dB dynamic range is demonstrated at room temperature and 35Vrms voltage.
