Notizen:
Time-division interferometry with 430 fs tunable laser pulses is used for direct femtosecond measurements of the wavelength dependence of the nonresonant nonlinear index of refraction, n2, in AlGaAs waveguides at room temperature. Below band-gap n2 values of ∼10−12 cm2/W are observed with resonant enhancement as the laser wavelength is tuned toward the band edge.
