Abstract: Automatic power equalization and stabilization of a liquid crystal enabled channel-selectable optical demultiplexer is demonstrated. The variation among output signals from different channels was reduced from similar to 10 dB to 0.15 dB with feedback control. The minimum ripple level of a single channel is similar to 0.05 dB. As a variable optical attenuator (VOA), the attenuation range of the device is similar to 12.6 dB. (c) 2007 Elsevier B.V. All rights reserved.
