Abstract-Continuous third harmonic generation in a terahertz driven modulated nanowire
We consider the possibility of observing continuous third-harmonic using a strongly driven, single-band one-dimensional metal. In the absence of the quantum efficiency of frequency tripling for such a system can be as high as 93%. Combining the Floquet quasi-energy spectrum with the Keldysh Green's function technique, we derive a semiclassical master equation for a one-dimensional band of strongly and rapidly driven in the presence of weak by The power absorbed from the driving field is continuously dissipated by modes, leading to a quasi-equilibrium in the distribution. We use the Kronig-Penney model with varying effective mass to establish the growth parameters of an InAs/InP near optimal for third harmonic at terahertz frequency range.
