Scalable high-repetition-rate sub-half-cycle terahertz pulses from spatially indirect interband transitions
We generate extremely asymmetric sub-half-cycle terahertz waveforms with scalable field strengths at megahertz pulse-repetition rates via ultrafast excitation of spatially indirect interband transitions in tailored quantum well heterostructures.
