ABSTRACT:
A flat-top arrayed waveguide grating with a Hyper-Gaussian distribution function and a modified sinc design exhibits a very low chromatic dispersion, low loss and requires a relatively small number of waveguides. Controlled loss is introduced into certain waveguides of the array by creating gaps (unguided regions) between the waveguides to produce a desired predetermined amplitude distribution. The gaps are preferably arranged in the middle of the array.
