Two-color solitons in Kerr third harmonic generation model

Alexey Sukhinin, Curtis Menyuk, Natalia Litchinitser +2

We investigate two-color, two dimensional spatially localized light modes in a resonant Kerr third-harmonic generation model. Using computational tools, we identify two distinct fa…

Hybrid Longitudinal-Transverse Propagating Electric Fields in Photonic Crystal Waveguides

Yanrong Zhang, Hooman Barati Sedeh, Christopher S. Whittington +3

In a uniform, source-free, and unbounded medium, Maxwell's equations require electromagnetic waves to be purely transverse. However, when a beam of light is tightly focused or stro…

Decoupling of topology and texture in optical skyrmions under turbulence

D. G. Pires, N. M. Litchinitser

Topological structure is widely invoked as a route to disorder-resilient photonic states, yet whether it protects locally resolved field structure under realistic disorder has not…

Nonlinear Nonlocal Metasurface for Harmonic Generation and Manipulation

Hooman Barati Sedeh, Yuruo Zheng, Jiaren Tan +7

The discovery of second harmonic generation in 1961 marked the birth of nonlinear optics, unlocking a range of applications from frequency conversion to quantum light generation. Y…
