Abstract

We demonstrate a variable optical attenuator (VOA) at lambda = 1.55 mum using 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 700 nm. A reflection type VOA with similar to0.24 ms response time and -32 dB dynamic range is demonstrated at room temperature and 35 V-rms voltage. (C) 2004 Optical Society of America.
