Abstract

In this paper, we design PHASAR(Phased Array) WDM(Wavelength Dvision Division Multi- and Demultiplexing) filters and evaluate their performance. The PHASAR WDM filter is designed to have flat-passband characteristics by inserting the multimode waveguides between input waveguides and a 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. The effect of the path difference error is also investigated.
