AbstractFor electron densities below a critical value, a double quantum well placed in a strong oscillating electric field produces a plateau of coherent harmonic radiation, which upconverts the driving frequency by up to two orders of magnitude. Continuous harmonic generation is made possible by energy relaxation and survives complete phase relaxation within a quarter-cycle of the driving field. Above a critical electron doping density, level bifurcation leads to abrupt changes in the wave function's phase and to the eventual disappearance of high harmonics.
