Self-phase modulation of a single-cycle terahertz pulse by nonlinear free-carrier response in a semiconductor

Dmitry Turchinovich, Jørn M. Hvam, Matthias C. Hoffmann

We demonstrate the self-phase modulation (SPM) of a single-cycle THz pulse in a semiconductor, using bulk n-GaAs as a model system. The SPM arises from the heating of free electron…
