Abstract
Passband broadening of arrayed waveguide filters that are compatible w ith singlemode fibre is demonstrated using an integrated multimode int erference coupler at the entrance to the star coupler. An 8 x 1.6nm fi lter is realised for the 1.55 mu m band with 0.75nm-wide -1dB passband s and -20dB rejection at >1.7nm bandwidth.
