Restricted Hilbert transform for non-Hermitian management of fields
W. W. Ahmed, R. Herrero, M. Botey +2
Non-Hermitian systems exploiting the synergy between gain and loss have recently become the focus of interest to discover novel physical phenomena. The spatial symmetry breaking in…
Photonic crystal spatial filtering in broad aperture diode laser
Sandeep Gawali, Darius Gailevičius, Guillermo Gerre-Werner +5
Broad aperture semiconductor lasers usually suffer from low spatial quality of the emitted beams. Due to the highly compact character of such lasers the use of a conventional intra…
Spatiotemporal stabilization proof of concept of Broad Area Semiconductor laser sources
J. Medina, W. W. Ahmed, S. Kumar +3
We provide a numerical proof of concept of a stabilization mechanism for BAS laser sources. The scheme is based on the simultaneous introduction of in-phase two-dimensional modulat…
Scattering properties of a PT dipole
K. Staliunas, P. Markoš, V. Kuzmiak
Electromagnetic response of PT-dipole is studied both analytically and numerically. In analytical approach, dipole is represented by two point scatterers. Within the first Born app…
All-dielectric self-cloaked structures
Zeki Hayran, Ramon Herrero, Muriel Botey +2
While practical realizations of optical invisibility have been achieved so far by various ingenious methods, they generally rely on complex materials which prevent the wide impleme…
