Focal-ratio-degradation (FRD) mitigation in a multimode fiber link using mode-selective photonic lanterns

Aurélien Benoît, Stephanos Yerolatsitis, Kerrianne Harrington +2

We present a new way to mitigate focal-ratio degradation (FRD) when using optical fibers to transport multimode light. Our approach exploits a custom multicore fiber (MCF) with six…
