Experimental Demonstration of Self-homodyne Coherent Transmission of TPS-4096-QAM over a 22.5 km MCF with a Spectral Efficiency of 19.15 bits/s/Hz/core

We experimentally demonstrate the self-homodyne coherent transmission of truncated probabilistic shaping (TPS) 4096-level quadrature amplitude modulation (QAM) over a 22.5 km 7-core fiber, without carrier recovery. The spectral efficiency can be up to 19.15 bits/s/Hz/core.
