We provide the first demonstration of two-color optical rectification from semiconductors in an extreme absorption regime. The THz generation is free from phase-matching constraints due to the confinement of the interaction within a 25-atomic-layer region.

Abstract
We provide the first demonstration of two-color optical rectification from semiconductors in an extreme absorption regime. The THz generation is free from phase-matching constraints due to the confinement of the interaction within a 25-atomic-layer region.
