The interaction between molecular electronic transitions and electromagnetic fields can be
enlarged to the point where distinct hybrid light–matter states, polaritons, emerge. The …

BACKGROUND One of the most important phenomena in cavity quantum electrodynamics
(cQED) is the so-called strong coupling regime, which appears when the interaction …

Here, we review the design of optical cavities, transient and modulated responses, and
theoretical models relevant to vibrational strong coupling (VSC). While planar Fabry–Perot …

Polariton lasers emit coherent monochromatic light through a spontaneous emission
process. As a rare example of a system in which Bose–Einstein condensation and …

Ten years ago, three teams experimentally demonstrated the first spasers, or plasmonic
nanolasers, after the spaser concept was first proposed theoretically in 2003. An overview of …

The invention and development of the laser have revolutionized science, technology, and
industry. Metal halide perovskites are an emerging class of semiconductors holding …
