Asymmetric Localization by Second Harmonic Generation
H. Ghaemi-Dizicheh, A. Targholizadeh, B. Feng +1
We introduce a nonlinear photonic system that enables asymmetric localization and unidirectional transfer of an electromagnetic wave through the second harmonic generation process.…
Compatibility of transport effects in non-Hermitian nonreciprocal systems
Hamed Ghaemi-Dizicheh, Henning Schomerus
Based on a general transport theory for non-reciprocal non-Hermitian systems and a topological model that encompasses a wide range of previously studied models, we (i) provide cond…
Spectral singularities and tunable slab lasers with 2D material coating
Hamed Ghaemi-Dizicheh, Ali Mostafazadeh, Mustafa Sarisaman
We investigate linear and nonlinear spectral singularities in the transverse electric and transverse magnetic modes of a slab laser consisting of an active planar slab sandwiched b…
Blowing up Light: A nonlinear amplification scheme for electromagnetic waves
Ali Mostafazadeh, Hamed Ghaemi-Dizicheh, Sasan Hajizadeh
We use blow-up solutions of nonlinear Helmholtz equations to introduce a nonlinear resonance effect that is capable of amplifying electromagnetic waves of particular intensity. To…
