Fundamental transfer matrix for electromagnetic waves, scattering by a planar collection of point scatterers, and anti-PT-symmetry
Farhang Loran, Ali Mostafazadeh
We develop a fundamental transfer-matrix formulation of the scattering of electromagnetic (EM) waves that incorporates the contribution of the evanescent waves and applies to gener…
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…
Spectral Singularities, Threshold Gain, and Output Intensity for a Slab Laser with Mirrors
Keremcan Doğan, Ali Mostafazadeh, Mustafa Sarısaman
We explore the consequences of the emergence of linear and nonlinear spectral singularities in TE modes of a homogeneous slab of active optical material that is placed between two…
Perfect Broadband Invisibility in Isotropic Media with Gain and Loss
Farhang Loran, Ali Mostafazadeh
We outline a method for constructing effectively two-dimensional isotropic optical media that are perfectly and omnidirectionally invisible for both TE and TM waves provided that t…
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…
