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…
Energy management strategy for an optimum control of a standalone photovoltaic-batteries water pumping system for agriculture applications
Mohammed Benzaouia, Hajji Bekkay, Abdelhamid Rabhi +3
Pumping water using multiple energy sources is the ideal solution for supplying of potable water in isolated or arid areas. In this paper, an effective control and energy managemen…
Quasi-normal mode theory of the scattering matrix, enforcing fundamental constraints for truncated expansions
Mohammed Benzaouia, John D. Joannopoulos, Steven G. Johnson +1
We develop a quasi-normal mode theory (QNMT) to calculate a system's scattering matrix, simultaneously satisfying both energy conservation and reciprocity even for a small trun…
Analytical criteria for designing multiresonance filters in scattering systems, with application to microwave metasurfaces
Mohammed Benzaouia, John D. Joannopoulos, Steven G. Johnson +1
We present general analytical criteria for the design of lossless reciprocal two-port systems, which exhibit prescribed scattering spectra satisfying $S_{22}(ω)=e^{iφ}S_{11}…
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…
From solar cells to ocean buoys: Wide-bandwidth limits to absorption by metaparticle arrays
M. Benzaouia, G. Tokic, O. D. Miller +2
In this paper, we develop an approximate wide-bandwidth upper bound to the absorption enhancement in arrays of metaparticles, applicable to general wave-scattering problems and mot…
