Abstract
We have demonstrated liquid-crystal WDM (wavelength-division-multiplexing) optical gain flatteners, as shown in Figures 1 and 2. They provide functionality of optical power equalization, tilting and profile manipulation using liquid-crystal modulators and harmonic synthesis approach. Liquid-crystal modulators utilize polarization manipulation without moving mechanical structures to process optical signals. This provides reliability of solid-state technologies. Liquid-crystal material has low absorption in the infrared wavelengths, so the devices could have low and uniform insertion losses over a wide spectral range. Since liquid-crystal modulators manipulate optical polarizations, one can utilize the known polarization states in the optical paths to minimize polarization-dependent losses. These advantages make liquid-crystal devices an attractive option for all-optical WDM signal processing.
