Waveguide Design For Minimum Nonlinear Effective Area And Switching Energy In Algaas At Half The Bandgap

Keywords

Abstract

The authors report a waveguide design which has been optimised to allow efficient, all-optical switching, in AIGaAs at half the bandgap. The effective area has been reduced to 6 μm2, allowing us to observe a nonlinear phase shift of > 5π. Nonlinear directional couplers, fabricated in the same material, exhibit a critical power of 42W of energy of 31 pJ. © 1995, IEE. All rights reserved.
