Abstract

We demonstrate a tunable OTDL using the orbital angular momentum modal domain to create the taps through mode-multicasting. We demonstrate 2-3 tap correlation and equalization. Equalization results show EVM improvement for a 20-Gbaud QPSK with chromatic dispersion of 20-km from EVM=26.3% to EVM=11.4%
