The device is also wavelength tunable and the spectral profile is selectable by appropriate grating design. This novel device is employed in a 2R-regenerator, enabling data rate reconfiguration and wavelength conversion, with negligible phase distortion. It will find application wherever a dispersionless reconfigurable bandpass optical filter is required.This work was produced with the assistance of the Australian Research Council under the ARC Centres of Excellence program.
