Semiconductor saturable absorbers for ultrafast THz signals

Matthias C. Hoffmann, Dmitry Turchinovich

Research output: Contribution to conference › Poster › Research › peer-review

Abstract

We demonstrate saturable absorber behavior of n-type semiconductors in the THz frequency range using nonlinear THz spectroscopy. Further, we observe THz pulse shortening and increase of the group refractive index at high field strengths.
