Lévy flights for light in ordered lasers
Erick G. Rocha, Emanuel P. Santos, Bruno J. dos Santos +4
Lévy flights for light have been demonstrated in disordered systems with and without optical gain, and remained unobserved in ordered ones. In the present letter, we investigate, n…
Real-time Phase Conjugation of Vector Vortex Beams
A. G. de Oliveira, M. F. Z. Arruda, W. C. Soares +4
Vector vortex beams have played a fundamental role in the better understanding of coherence and polarization. They are described by spatially inhomogeneous polarization states, whi…
Non-Hermitian spectral changes in the scattering of partially coherent radiation by periodic structures
Paulo A. Brandão, S. B. Cavalcanti
The physical aspects of partially coherent radiation interacting with deterministic non-Hermitian periodic materials remain largely unexplored in the statistical optics literature.…
Scattering of partially coherent radiation by non-Hermitian localized structures having Parity-Time symmetry
Paulo. A. Brandão, Solange B. Cavalcanti
A theoretical model based on two-point scatterers is suggested to investigate scattering of partially coherent radiation by a non-Hermitian localized structure, invariant under the…
