Soliton propagation in multimode optical fibers [PDF]

Optics Letters, 1981
Soliton propagation in a multimode optical fiber in the presence of an intensity-dependent refractive index is investigated by means of a set of nonlinear coupled equations derived in the frame of coupled-mode theory. In particular, the conditions on modal amplitudes and modal dispersion necessary for soliton existence are derived.

A multimode fiber refractive index sensor [PDF]

2016 IEEE SENSORS, 2016
We present a simple refractive index sensor based on multimode fibers realized by stripping three different lengths of cladding. We theoretically explain and experimentally validate three mechanisms occurring in the multimode fiber for sensing surrounding refractive index.

Wavy‐Interlocked Stretchable Triboelectric Nanogenerators Enhanced by Liquid Metal Microflowers for Self‐Powered Wearable Motion Monitoring

Advanced Science, EarlyView.
Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...
