Nonlinear optical properties of quantum‐confined GaAs nanocrystals in Vycor glass

Quantum‐confined nanocrystallites of GaAs are fabricated in porous Vycor glass and the bound electronic nonlinear refractive index, the two‐photon absorption coefficient, and the refraction from carriers generated by two‐photon absorption are simultaneously determined using the Z‐scan method and compared to those of bulk GaAs. The measured nonlinear refractive index is an order of magnitude larger than that of bulk GaAs at 1060 nm.
