Abstract

Owing to the promising application prospect of mode division multiplexing technology, reconfigurable optical mode multiplexers/demultiplexers, which enable convenient construction of flexible and complex on-chip optical networks, have attracted increasing attention in the academic community. Here, we propose and experimentally demonstrate a reconfigurable two-mode multiplexer/demultiplexer based on novel three-waveguide-coupling structures. The fabricated device can multiplex two input signals to fundamental and first-order quasi-transverse electric modes with large operation bandwidth. Static response spectra show that the optical crosstalk at the output ports of the device are less than -14.3 dB and -13.7 dB over the entire C band (> 40 nm), respectively. The highspeed data transmission ability of 40 Gbps for each multiplexing channel are also demonstrated successfully. The presented device is believed to be a potential candidate for future on-chip optical network with large-scale integration, flexible functionality, and low cost.
