A novel scrambling-type mode multiplexer (MUX) is proposed for future mode-division multiplexing with large number of modes. The proposed MUX does not aim at high modal extinction ratio as in a ...

We propose an original two-mode (TE0/TE1) division multiplexer using a taper-etched directional coupler. The multiplexer has a low insertion loss of -0.1 dB within C-band with a minimum loss of -0.05 ...
