Full‐Control and Switching of Optical Fano Resonance by Continuum State Engineering (Adv. Sci. 32/2023)

Fano Resonance In article number 2304310, Hae-Gon Jeon, Young Min Song, and co-workers demonstrate full-control of Fano resonance, enabling the design of a spectrum from quasi-Lorentzian to Lorentzian to Fano shapes. Modulating the porosity of the continuum state results in the successful creation of an actively tunable color filter and an optical bio-particle detector. Inverse design is employed to optimize the design process.
