Intermodal all-optical pulse switching and frequency conversion using temporal reflection and refraction in multimode fibers [PDF]
NanophotonicsIn 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 ...
