Abstract :
A triplexer based on silicon nanophotonic wire structure consisting of two Bragg grating-assisted directional couplers is proposed, which can multi/demultiplex three different wavelengths through a compact device. The device has low loss, low crosstalk, and a footprint of only 210 ×40 µm. The 1-dB bandwidth for the three channels located at 1310, 1490 and 1550 nm are 110, 20, and 20 nm, respectively.
