Physical Review A, 89(2).||Series/Report no.:||Physical review A||Abstract:||We develop the microscopic theory of a terahertz (THz) laser based on the effects of resonant tunneling in a double quantum well heterostructure embedded in both optical and THz cavities. In the strong-coupling regime the system hosts dipolaritons, hybrid quasiparticles formed by the direct exciton, indirect exciton, and optical photon, which possess large dipole moments in the growth direction. Their radiative coupling to the mode of a THz cavity combined with strong nonlinearities provided by exciton-exciton interactions allows for stable emission of THz radiation in the regime of the continuous optical excitation. The optimal parameters for maximizing the THz signal output power are analyzed.||URI:||https://hdl.handle.net/10356/104018
