An eleven-wavelength-switchable thulium-doped fiber laser was proposed and demonstrated, incorporating an improved geta-shaped cavity providing bidirectional amplification, and a sandwich four-mode fiber Mach–Zehnder interferometer filter with curvature sensitivity. The filter was fabricated by splicing a segment of four-mode fiber (FMF) between two segments of a no-core fiber (NCF), with two segments

Spin-splitting and spin Hall effect of reflected Airy beams on the surface of topological insulator Results Phys. (IF 5.3) Pub Date : 2024-03-27 Di Yu, Haoyuan Song, Yubo Li, Yuqi Zhang, Qiang Zhang, Shufang Fu, Xuanzhang Wang
We present an analysis of the enhanced spin Hall effect of light (SHEL) resulting from a reflected Airy beam off the interface of an air-topological insulator (TI). Our study suggests that the surface conductivity of TI film and the decay factors of Airy beams are crucial in increasing the spin-splitting distance and the spatial shifts of the left-handed circularly polarized (LCP) and right-handed

Solitary wave solutions for the (1+1)-dimensional nonlinear Kakutani–Matsuuchi model of internal gravity waves Results Phys. (IF 5.3) Pub Date : 2024-03-27 Mostafa M.A. Khater, Suleman H. Alfalqi
The Kakutani–Matsuuchi () equation provides a mathematical framework for studying the dynamics of extended nonlinear internal gravity waves in a stratified fluid medium, including important phenomena such as solitary wave propagation. This study explores various analytical and semi-analytical methods to obtain accurate solutions for the (1+1)-dimensional model.
