Interacting plexcitons for designed ultrafast optical nonlinearity in a monolayer semiconductor

HIGHLIGHTS

• who: Yuxiang Tang from the (UNIVERSITY) have published the research work: Interacting plexcitons for designed ultrafast optical nonlinearity in a monolayer semiconductor, in the Journal: (JOURNAL)
• what: The authors explore a class of peculiar polaritons named plasmon-exciton polaritons (plexcitons) in a hybrid system composed of silver nanodisk arrays and monolayer tungsten-disulfide (WS2) which shows giant room-temperature nonlinearity due to their deep-subwavelength localized nature. The authors demonstrate this giant nonlinearity can be exploited to manipulate the ultrafast nonlinear absorption properties of the solid-state system. The authors provide experimental evidence of nontrivial . . .
