Abstract :
We have theoretically studied the frequency transformation of a strong electromagnetic pulse in lateral semiconductor superlattices associated with excitation of self-consistent electric field-driven Bloch oscillations. The necessary conditions for observation of Bloch oscillator emission of radiation have been found. The energy efficiency of the frequency multiplication and spectral composition of THz radiation transmitted through a superlattice have been calculated.
