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…
Deep Learning Driven Enhancement of Optical Vortex Line Robustness in Atmospheric Turbulence
Dmitrii Tsvetkov, Danilo Gomes Pires, Natalia Litchinitser
The stability of optical vortex structures in turbulent environments is critical for their applications in optical communication, quantum information, and structured light technolo…
Structuring Polarization States of Light in Space and Time
Danilo Gomes Pires, Jiaren Tan, Hooman Barati Sedeh +1
The spatiotemporal sculpturing of light beams with arbitrary phase and polarization topologies has garnered significant attention in recent years due to its potential to advance op…
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…
