Abstract
In this paper, for the first time, we propose a photonic-aided digital-to-analog converter (PADAC) to break through transmitter-side bandwidth limitation in intensity modulation and direct detection (IM-DD) systems. By this method, bandwidth of receiver-side devices can be fully utilized, and nonlinear distortions in high-data-rate electrical signals are avoided.
Experimental results indicate that, with only linear equalization, 120 GBaud PAM-4 and PAM-6 signals have been successfully generated and detected below 6.25%-OH HD-FEC and 20%-OH SD-FEC limits, respectively.
