Abstract :
A new method to broaden the passband of arrayed-waveguide grating routers is proposed. A sinc(x) intensity distribution is formed in the array by a slot etched in the input star coupler. A 3 dB bandwidth of 65 GHz is obtained for a 100 GHz channel spacing and the adjacent channel crosstalk is less than 25 dB.
