Abstract

We propose a planar lightwave circuit (PLC)-based mode multi/demultiplexer (MUX/DEMUX) with an asymmetric parallel waveguide for mode division multiplexed (MDM) transmission. The PLC-based mode MUX/DEMUX has advantage of selectively exciting higher-order mode. We realize three-mode (LP01, LP11a, and LP21a) multiplexing by using an asymmetric parallel waveguide. We then design and fabricate a PLC-based mode MUX/DEMUX on one chip by using our proposed LP11 mode rotator to allow us to utilize the LP11b mode. We successfully multiplex the LP01, LP11a, and LP11b modes and achieve a relatively low insertion loss over the C-band using our fabricated mode MUX/DEMUX. Our results indicate that the PLC-based mode MUX/DEMUX with a uniform height has the potential to increase the mode number by using an LP11b mode.
