Abstract

We demonstrate the arbitrary control of the carrier-envelope phase of intense few-cycle THz pulses by using a simple passive component with high transmission efficiency based on a parallel metal plate waveguide. In this component, the carrier-envelope phase is altered by using the difference between the group and phase velocities. We demonstrate pulseshape- dependent nonlinear spectroscopy using these passive optics for Ge:Sb, where strong transitions between the shallow acceptor levels are located at 2.0 THz.
