Abstract
- We present theoretical and experimental studies of the amplitude of the terahertz (THz) light emitted by biased superlattices excited by fast optical pulses as a function of the pump photon energy. The comparison of the measured transient signal and of its dependence upon the excitation photon energy with a model calculation allows a clear separation between the contributions of the dissociated carriers and bound pairs to the emitted THz field.
