Accelerated nonlinear interactions in graded-index multimode fibers [PDF]
Multimode optical fibers can be used to observe complex intermodal processes like optical solitons. Here, Eftekhar et al. study accelerated nonlinear interaction in multimode fibers with a tapered core diameter and its effect on the temporal and spectral

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

Mitigating stimulated Brillouin scattering in multimode fibers with focused output via wavefront shaping [PDF]
The key challenge for high-power delivery through optical fibers is overcoming nonlinear optical effects. To keep a smooth output beam, most techniques for mitigating optical nonlinearities are restricted to single-mode fibers.

Mode multiplexer for multimode transmission in multimode fibers
We have numerically demonstrated an efficient mode multiplexer which can tailor the input field patterns by using a phase controller and a mode coupler formed by four single-mode fibers (SMFs). By connecting the mode multiplexer to a multimode fiber (MMF), two orthogonal higher-order modes of the MMF can be simultaneously excited to form two ...

Spatiotemporal control of ultrafast pulses in multimode optical fibers [PDF]
Multimode optical fibers represent the ideal platform for transferring multidimensional light states. However, dispersion degrades the correlations between the light’s degrees of freedom, thus limiting the effective transport of ultrashort pulses between
