Nonlinear exceptional-point lasing with ab-initio Maxwell-Bloch theory
Mohammed Benzaouia, A. D. Stone, Steven G. Johnson
We present a general analysis for finding and characterizing nonlinear exceptional point (EP) lasers above threshold, using steady-state ab-initio Maxwell-Bloch equations. For a sy…
Is single-mode lasing possible in an infinite periodic system?
Mohammed Benzaouia, Alexander Cerjan, Steven G. Johnson
In this Letter, we present a rigorous method to study the stability of periodic lasing systems. In a linear model, the presence of a continuum of modes (with arbitrarily close lasi…
Approaching the upper limits of the local density of states via optimized metallic cavities
Wenjie Yao, Mohammed Benzaouia, Owen D. Miller +1
By computational optimization of air-void cavities in metallic substrates, we show that the local density of states (LDOS) can reach within a factor of of recent theor…
Inverse Design of Nanoparticles for Enhanced Raman Scattering
Rasmus E. Christiansen, Jérôme Michon, Mohammed Benzaouia +2
We show that topology optimization (TO) of metallic resonators can lead to improvement in surface-enhanced Raman scattering (SERS) efficiency compared to traditio…
Limits to surface-enhanced Raman scattering near arbitrary-shape scatterers
Jérôme Michon, Mohammed Benzaouia, Wenjie Yao +2
The low efficiency of Raman spectroscopy can be overcome by placing the active molecules in the vicinity of scatterers, typically rough surfaces or nanostructures with various shap…
