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