Abstract
We compute the third harmonic field generated by Bloch-oscillating electron s in a quasioptical array of superlattices under THz irradiation. The third harmonic power transmitted oscillates with the internal electric field, wi th nodes associated with Bessel functions in eEd/(h) over bar omega. The no nlinear response of the array causes the output power to be a multivalued f unction of the incident laser power. The output can be optimized by adjusti ng the frequency of the incident pulse to match one of the Fabry-Perot reso nances in the substrate. Within the transmission-line model of the array, t he maximum conversion efficiency is 0.1%. (C) 1999 American Institute of Ph ysics. [S0003-6951(99)01215-2].
