Intermodal all-optical pulse switching and frequency conversion using temporal reflection and refraction in multimode fibers

Nanophotonics
In this work, we extend temporal reflection and refraction analogies from the case of singlemode optical fibers to multimode fibers. Specifically, we show that nonlinear multimode fibers provide novel degrees of freedom that permit us to control optical ...

Nonlinear Refraction and Absorption of Ag₂₉ Nanoclusters: Evidence for Two-Photon Absorption Saturation

, 2018
We report the nonlinear absorption and refraction of Ag29 nanocluster aqueous suspensions using the open and closed aperture Z-scan method at 532 nm. The stoichiometry of the atomically precise silver nanoclusters has been determined by mass spectrometry,
