Abstract
AWG designed in this paper is considered with flat passband characteristics in the channel as a method for solving frequency stability problems of the sources in the conventional optical filters. This device can acquire the flat passband characteristics by inserting the multimode wave guides utilizing the self imaging effec between input wave guides and first star coupler. BPM simulation results show that the excess loss is smaller than 6.5 dB, the crosstalk is less than -22 dB and the 1 dB passband is about 50 GHz in the central channel.
