Abstract

In this paper, we demonstrate a complete suppression of coherent Rayleigh noise in a bi-directional fiber link using a modelocked laser transmitter. The noise suppression arises because optical beat interference at the receiver occurs mostly at frequencies beyond the receiver bandwidth, and cannot contribute to RF noise. Our results suggest that noise from multi-path interference in general can be reduced dramatically by use of spectrally-sliced transmitters
