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.…
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…
Nonlinear Spectral Singularities and Laser Output Intensity
Hamed Ghaemi-Dizicheh, Ali Mostafazadeh, Mustafa Sarisaman
The mathematical notion of spectral singularity admits a description in terms of purely outgoing solutions of a corresponding linear wave equation. This leads to a nonlinear genera…
