Modulation instability (MI) is a fundamental nonlinear phenomenon whereby continuous optical waves become unstable, giving rise to the spontaneous breakup into pulse trains. This effect, driven by the ...

This figure illustrates the result of distributed temperature sensing using a perfluorinated graded-index plastic optical fiber (POF). The top diagram shows the structure of the sensing POF, including ...

- The breakthrough leverages international-standard-compliant, cutoff-shifted optical fibers with a novel approach that triples the capacity of certain spectral regions using spatial-division ...
