Abstract
We report on spectral interferometry for measuring the spectrally resolved nonlinear phase and amplitude response in a pump–probe experiment. Using nJ pulses from a femtosecond oscillator, we demonstrate the method by measuring the nonlinear response of a GaAs∕AlGaAs single-quantum-well saturable absorber mirror. The demonstrated sub-mrad phase sensitivity constitutes a two-order-of-magnitude improvement of phase resolution, compared to earlier demonstrations. Dynamic spectral interferometry proves to be a powerful tool for evaluating the phase response on nonlinear optical semiconductor devices for mode locking of lasers, optical switching, and other photonic applications.
