Linear Systems Approach to Describing and Classifying Fano Resonances (Postprint)

Abstract

We have shown that asymmetric resonant line shapes derived elsewhere from rigorous electromagnetic calculations and from the two-oscillators model can also be obtained by treating the photonic resonance as a response of a first-order linear system. We have reformulated the line shape equation into a weighted sum of the Fano and Lorentzian line shapes and proposed a two-parameter classification scheme with one parameter being the asymmetry factor in the original Fano formula and the other one being the relative weight of the Fano and Lorentzian line shapes.
