Mode Division Multiplexed Coherent Optical Transmission in Time Domain by Using Higher-Order Hermite-Gaussian Pulses (W2B.19)

Presenter: Masataka Nakazawa, Tohoku University

We propose a new mode-division-multiplexing (MDM) technique in time-domain using higher-order Hermite-Gaussian pulses. 32-QAM, 450-km MDM transmission was successfully demonstrated with HG0, HG1, HG2, and HG3 pulses, where the time-domain orthogonality was used for demultiplexing.
