Abstract

We present a nonlinear optical loop mirror (NOLM)-based $160\mathrm{Gbits}∕\mathrm{s}$ demultiplexer built with a new generation of silica-based nonlinear fibers. Together with the record-breaking length of only $11\mathrm{m}$, the demonstrated NOLM has a relatively low control signal power, which is comparable to the best results for bismuth-oxide fibers to date, resulting in a four-times smaller power-length product than any previous silica fiber. Further, unlike previous silica-based approaches, the demonstrated demultiplexer does not require any dispersion management because of its extremely short length. The device is operable with a randomized input polarization at a bit error rate of ${10}^{-8}$.
