“…Particularly, the breaking of inversion symmetry opens optical transitions at the Rabi frequency at QDs placed in strong external laser field [20]. The similar effect occurs for asymmetric quantum wells placed inside a planar microcavity [21,22]. In current manuscript we consider modification of the emission spectrum of asymmetric QDs inside a single-mode microcavity using fully quantum approach.…”

We have investigated theoretically the interaction between individual quantum dot with broken inversion symmetry and electromagnetic field of a single-mode quantum microcavity. It is shown that in the strong coupling regime the system demonstrates nonlinear optical properties and can serve as emitter of the terahertz radiation at Rabi frequency of the system. Analytical results for simplest physical situations are obtained and numerical quantum approach for calculating emission spectrum is developed.

“…For instance, a THz emitter based on transitions between upper and lower polariton branches was considered in Refs. [13][14][15]. Another possible scheme exploits the THz range transition between 2p and 1s states of the exciton, the former being a dark state and the latter coupled to the cavity mode.…”

We propose a scheme of continuous tunable THz emission based on dipolaritons -mixtures of strongly interacting cavity photons and direct excitons, where the latter are coupled to indirect excitons via tunnelling. We investigate the property of multistability under continuous wave (CW) pumping, and the stability of the solutions. We establish the conditions of parametric instability, giving rise to oscillations in density between the direct exciton and indirect modes under CW pumping. In this way we achieve continuous and tunable emission in the THz range in a compact single-crystal device. We show that the emission frequency can be tuned in a certain range by varying an applied electric field and pumping conditions. Finally, we demonstrate the dynamic switching between different phases in our system, allowing rapid control of THz radiation.

“…Recently novel approaches to THz generation have been formulated, solving the problem of the lifetime mismatch by exploiting polariton-polariton scattering, that allows to increase the emission rate through stimulation of the final state polaritonic population [85][86][87][88][89]. Some of the basic concepts on which these proposals are based are presently being tested experimentally.…”

Bosonic lasers represent a new generation of coherent light sources. In contrast to conventional, fermionic, lasers they do not require inversion of electronic population and do not rely on the stimulated emission of radiation. Bosonic lasers are based on the spontaneous emission of light by condensates of bosonic quasiparticles. The first realization of bosonic lasers has been reported in semiconductor microcavities where bosonic condensates of exciton-polaritons first studied several decades ago by K.B. Tolpygo can be formed under optical or electronic pumping. In this paper we overview the recent progress in the research area of polaritonics, address the perspective of realization of polariton devices: from bosonic cascade lasers to spin transistors and switches.
