Free-carrier assisted optical nonlinearity in WSe2 thin films near the optical communication band

Km. Surbhi and Ritwick Das

Not Accessible

Your library or personal account may give you access

Abstract

We present an investigation that reveals the impact of free carriers on the nonlinear absorption in WSe2 thin-film. The sample exhibits strong two-photon absorption behaviour at 1520 nm excitation wavelength.
