AbstractA compact and broadband mode (de) multiplexer utilizing the asymmetrical directional coupling between a hybrid plasmonic waveguide and a silicon nanowire waveguide is proposed. The coupling length is 13.6 mu m, which is the shortest in TE0 and TE1 mode multiplexers reported, to the best of our knowledge. It shows a high mode conversion efficiency of 99.2% with excess loss of only 0.35 dB at 1550 nm. The mode multiplexing circuit exhibits a low crosstalk of less than -17 dB over a large bandwidth of 100 nm. (C) 2014 Optical Society of America
