%0 Generic %D 2013 %T Silicon CWDM Demultiplexers Using Contra-Directional Couplers %A Shi, Wei %A Yun, Han %A Lin, Charlie %A Wang, Xu %A Flueckiger, Jonas %A Jaeger, Nicolas %A Chrostowski, Lukas %P CTu3F.5 %X We experimentally demonstrate ultra-compact (<0.008mm2), 4-channel CWDM demultiplexers using silicon photonic contra-directional couplers. Flat-top passbands of 10nm, insertion loss of lower than 1dB, and crosstalk of -20dB have been obtained. %8 06/2013
