From: Generalized Fano lineshapes reveal exceptional points in photonic molecules
Generalized Fano lineshapes in a disordered photonic medium. a Scanning electronic microscope image of the disordered GaAs slab along with the photoluminescence (PL) intensity maps of two spectrally separated resonances superimposed in green and red, respectively. The scale bar is 500 nm. b–e Comparison between PL and resonant-scattering (RS) spectra detected at the positions A, B, C, D. The PL (RS) data are plotted as blue (red) points. PL data are fitted by Lorentzian (blue lines). b The RS spectrum of resonance 1 is reproduced by a standard Fano lineshape (green line). c–e The RS spectra of resonance 2 are reproduced by generalized Fano profiles (red lines). At every position, the central frequency and the broadening of PL and RS spectra are in agreement
