We transmit over all 30 spatial and polarization modes of a 22.8-km multimode fiber. 15-mode photonic lanterns enabled low-loss coupling into and out of the fiber and a time-multiplexed coherent receiver facilitates measurement of all 30 signals.
This letter presents a 10-Gb/s burst-mode clock and data recovery (BM-CDR) circuit based on an analog phase-picking method. The experiment demonstrates that the proposed BM-CDR circuit is able to align the BM data to a local clock with a phase alignment accuracy of , a 25-ns latency and zero bit loss. The circuit further resamples the aligned data using the local clock for jitter reduction...
