Numerical and Analytical Studies of Graphene Saturable Absorption

Not Accessible

Your library or personal account may give you access

Abstract

We present the saturation of absorption on graphene, calculating the optical conductivity numerically and analytically. We verify the validity of our calculations for higher photon energies and show that the saturation behavior on graphene is 1/1+3S, due to the superposition of several two-level systems.
