Bi-directional top hat D-Scan for characterization of third order nonlinear waveguides

Not Accessible

Your library or personal account may give you access

Abstract

The effective Kerr and two photon absorption (TPA) nonlinear parameters of a nano-waveguide are characterized by means of a bi-directional top hat D-Scan technique. This approach requires a single beam and allows the measurement of the coupling efficiencies.
