Abstract
Inter-channel crosstalk for a liquid crystal-based dynamic channel blocker/equalizer has been experimentally studied. With the optimal interpixel width, a 32-channel, 100-GHz channel-spacing sample is fabricated and characterized. The maximum insertion loss (IL) of 5 dB and the polarization dependent loss (PDL) of 0.5 dB within the ITU ± 14 GHz are achieved. The 45 dB extinction ratio is obtained. The variations of the IL and PDL within the temperature range from - 5°C to 65°C cross the C-band are less than 1 dB and 0.4 dB respectively.
