Phase-matching-induced near-chirp-free solitons in normal-dispersion fiber lasers
The fiber birefringence, chromatic dispersion, and nonlinear effect follow a phase-matching principle, enabling the formation of birefringence-managed solitons in normal-dispersion fiber lasers containing a section of polarization-maintaining fiber.

MXene supported surface plasmons on telecommunications optical fibers
We demonstrate that MXenes can support surface plasmons at telecommunications wavelengths (1550nm) and show that surface plasmon polariton resonances can be excited on MXene coated single mode optical fibers.
