摘要

Abstract

Searching for ideal materials with strong effective optical nonlinear responses is a long-term task enabling remarkable breakthroughs in contemporary quantum

and nonlinear optics. Polaritons

hybridized light-matter quasiparticles

are an appealing candidate to realize such nonlinearities. Here

we explore a class of peculiar polaritons

named plasmon–exciton polaritons (plexcitons)

in a hybrid system composed of silver nanodisk arrays and monolayer tungsten-disulfide (WS

)

which shows giant room-temperature nonlinearity due to their deep-subwavelength localized nature. Specifically

comprehensive ultrafast pump–probe measurements reveal that plexciton nonlinearity is dominated by the saturation and higher-order excitation-induced dephasing interactions

rather than the well-known exchange interaction in traditional microcavity polaritons. Furthermore

we demonstrate this giant nonlinearity can be exploited to manipulate the ultrafast nonlinear absorption properties of the solid-state system. Our findings suggest that plexcitons are intrinsically strongly interacting

thereby pioneering new horizons for practical implementations such as energy-efficient ultrafast all-optical switching and information processing.
