Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

ABSTRACT Thin dielectric films are known to show distinct colors, depending primarily on the film thickness. In the present article we show that a specialized thin film Fabry–Pérot resonator, that we name conductor–dielectric–conductor (CDC) matched cavity, appears grey when obse...

Ultrafast switching of optical properties in a doped semiconductor by intense femtosecond laser pulses

The rapid switching of materials when excited by ultrashort pulses of light is central for many optical technologies, and in particular to the developing field of time-varying metamaterials. These out-of-equilibrium interactions are difficult to capture with traditional theoretic...
