We report the first observation of enhanced third-order nonlinear effects in AlGaAs nanowires. AlGaAs nanowaveguides with widths varying from 100 to 600nm were fabricated and characterized. Nonlinear phase shifts of ∼π were experimentally observed at 1.55μm with peak powers of 30-40W in 600μm long, 550nm wide guides.

Abstract
We report the first observation of enhanced third-order nonlinear effects in AlGaAs nanowires. AlGaAs nanowaveguides with widths varying from 100 to 600nm were fabricated and characterized. Nonlinear phase shifts of ∼π were experimentally observed at 1.55μm with peak powers of 30-40W in 600μm long, 550nm wide guides.File in questo prodotto:
