Dielectric waveguide optimisation for GaAs based quantum cascade lasers

Not Accessible

Your library or personal account may give you access

Abstract

Significant improvements in the threshold current density and in the slope efficiency of GaAs quantum cascade lasers are obtained by using dielectric waveguides based on Al xGa1−xAs and Ga0 49In0.51P cladding layers.
