In this work, we present an experimental demonstration of real-time transoceanic space-division multiplexed transmission with coupled-core multicore fibers. To compensate for modal coupling in the …
In this study, we demonstrate laser phase noise measurement with a 0.8-s period and an 800-ps temporal resolution. An optical carrier is received by heterodyne detection, and the detected electrica…
Probabilistic shaping (PS) has been widely studied and applied to optical fiber communications. The encoder of PS expends the number of bit slots and controls the probability distribution of channe…
