We demonstrate active management of 8 nm/spl times/0.8 nm wavelength-division multiplexing (WDM) channels with arbitrary dropping/passing and channel equalization. The optical/add-drop-(de)multiplexing functionality is achieved using a polarization-insensitive spatial-light-modulator-based holographic filter. Finer resolution (50 GHz) and spectral shaping(More)
We report equalisation of eight 3-4 nm-spaced WDM channels amplified by a non-gain-flattened EDFA. The 9.5 dB spectral gain range is reduced to 0.75 dB. Flattening of the filter passband has been experimentally demonstrated The dynamic holographic technology is based on a 128/spl times/128 pixellated FLC SLM (ferroelectric liquid crystal spatial light(More)
