Abstract: | Eight-channel simultaneous wavelength conversion from equal to unequal wavelength-division-multiplexing (WDM) channel spacing is successfully demonstrated using two arrayed-waveguide-gratings (AWGs) and cross-gain modulation (XGM) in a spot-size converter-integrated semiconductor optical amplifier array on a planar-lightwave-circuit platform. The input AWG concurrently demultiplexed both the equal-spaced WDM signal and unequal-spaced pump lights to couple a pair comprising a signal and a pump for the XGM. Only a small power penalty of less than 0.5 dB was observed for all eight channels. The receiver sensitivity at 2.5 Gb/s was -33 dBm for all eight channels |
