Description
Summary:The concept of ultrafast light modulator for wavelength ∼1.5 μm controlled by fundamental harmonic of a Ti:Al2O3 laser has been demonstrated. The possibility of realization of this concept was experimentally confirmed. We have demonstrated strong spectrally wide nonlinear response in multilayer heterostructures based on GaAs/(AlGa)xOy with the relaxation time of 1–3 ps in the spectral range where both materials have negligible absorption.
