We firstly show the operation principle and basic characteristics Revised 3 August 2016 of PLC-based MUX/DEMUXs with an asymmetric directional coupler (ADC). We then demonstrate the Accepted 4 August 2016 3-mode (2LP-mode) multiplexing of the LP01, LP11a, and LP11b modes by using fabricated PLC-based mode Available online 18 August 2016 MUX/DEMUX on one chip. In order to excite LP11b mode in the same plane, a PLC-based LP11 mode rotator is introduced. Finally, we show the PLC-based 6-mode (4LP-mode) MUX/DEMUX with a uniform height Keywords: by using ADCs, LP11 mode rotators, and tapered
