Abstract :
By measuring the phase and amplitude distribution of the optical paths in a flatband arrayed waveguide grating, the array mask was redesigned to correct for the slow varying phase errors within the array waveguides, leading to a reduction in both the chromatic dispersion across the passband of the device and in the transmission band tilt.
