Tunable single-photon emission from dipolaritons

Abstract

Abstract. We study a system comprising of a double quantum well embedded in a micropillar optical cavity, where strong coupling between a direct exciton, indirect exciton, and cavity photon is achieved. We show that the resulting hybrid quasiparticles -dipolaritons -can induce strong photon correlations and lead to anti-bunched behaviour of the cavity output field. The origin of the observed single photon emission is attributed to unconventional photon blockade. Moreover, we find that the second-order equal time correlation function g (2) (0) can be tuned over a large range using an electric field applied to the structure, or changing the frequency of the pump. This allows for an on-the-flight control of cavity output properties, and is important for the future generation of tunable single photon emission sources.

Tunable photon statistics in weakly nonlinear photonic molecules

“…Because as η → +∞, we have opt → 0 and U opt → 0 from Eqs. (24) and (25), which do not agree with the results given in Eqs. (2) and (3) for the case of ε b = 0.…”

“…From Eqs. (24) and (25), the optimal conditions for strong antibunching are dependent on the strength ratio between the driving fields η. This implies that we can control the statistic properties of the photons by tuning the strength ratio between the two driving fields.…”

“…So it should be interesting to create tunable single-photon sources where the optimal conditions for strong antibunching are related to some controllable parameters in experiments. Kyriienko et al proposed a tunable * liyong@csrc.ac.cn single-photon emission from dipolaritons by embedding a double quantum well in a micropillar optical cavity [24]. They found that the equal-time second-order correlation function of the dipolaritons in the hybrid system can be tuned by using an electric field applied to the structure, or changing the frequency of the pump.…”

Floquet control of dipolaritons in quantum wells

“…After the first experimental observation of dipolaritons [24], it was demonstrated that they have distinct response to electric and magnetic fields [29] and stronger interparticle interaction as compared to conventional polaritons [30]. Moreover, they can be used for enhanced electrical control [31,32], facilitate indirect exciton condensate preparation [33], single photon emission [34], and other optoelectronic applications. Particularly, it was predicted that dipolaritons can serve as an efficient ter-ahertz emission source [35][36][37].…”

Selective excitations of a Kerr-nonlinear resonator: exactly solvable approach

“…The strong photon-photon correlation in this scheme is attributed by the destructive quantum interference between distinct driven-dissipative pathways [20,21]. Based on this mechanism, many different systems are proposed to realize the unconventional photon-blockade [22][23][24][25][26][27][28][29], moreover three oscillatory mode systems have also been considered [30].…”
