Abstract

In this article we discuss a model describing key features concerning the\nlineshapes and the coherent absorption conditions in Fano-resonant dissipative\ncoupled oscillators. The model treats on the same footing the weak and strong\ncoupling regimes, and includes the critical coupling concept, which is of great\nrelevance in numerous applications; in addition, the role of asymmetry is\nthoroughly analyzed. Due to the wide generality of the model, which can be\nadapted to various frameworks like nanophotonics, plasmonics, and\noptomechanics, we envisage that the analytical formulas presented here will be\ncrucial to effectively design devices and to interpret experimental results.\n
