| 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 ∼10 dB to 0.15 dB with feedback control. The minimum ripple level of a single channel is ∼0.05 dB. As a variable optical attenuator (VOA), the attenuation range of the device is ∼12.6 dB. |
