Paper Abstract

The capabilities for practical all-optical switch (AOS) operation, being picosecond switching times and femtojoule switching energies, are investigated in this work. Two distinct nanophotonic architectures are introduced. The first nanophotonic architecture uses nanostructures, in the form of semiconductor nanoparticles, to enhance the rate of surface recombination and provide picosecond switching times. Switching times down to 4.5 ps are demonstrated. The second architecture uses photonic nanoinjection, with high refractive index spheres, to create high-intensity pump-probe beam interaction at a GaAs surface. This architecture offers 10 ps switching times with switching energies as low as 50 fJ. Nanophotonic architectures such as these can provide the capabilities needed for future AOS implementations.
