Spatially Coherent Interlayer Exciton Lasing in an Atomically-Thin Heterostructure

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate lasing in WSe2-MoSe2 heterostructure integrated in a silicon nitride grating cavity. Signatures of lasing include sharp increase in spatial coherence and super-linear increase in the emission intensity as photon number increases above unity.
