Generating Ultrashort THz Waveforms from Shifting Electrons in Asymmetric Quantum Wells

A time-dependent electric current emits an electromagnetic wave, a basic physical effect exploited in telecom antennas. Transferring this mechanism to the ultrashort length and time scales of the quantum world allows for generating intense picosecond terahertz (THz) pulses in asymmetric semiconductor quantum structures.
