Abstract:
Hybrid microcavity for single quantum dot based emitters has been developed and realized. The microcavity consists of semiconductor distributed Bragg reflector and microlens, which is selectively positioned over a single (111) In(Ga)As quantum dot. We have demonstrated pure single photon emission with $g^{(2)}(\tau)$; $g^{(2)}(0)$ = 0.07. The fine structure of exciton states of (111) In(Ga)As quantum dots is studied. It is shown that the splitting of exciton states is comparable with the natural width of exciton lines, which is of great interest for the design of emitters of pairs of entangled photons on the basis of these quantum dots.
Keywords:
quantum dots, single-photon sources, photon-pair sources, fine structure of exciton states.
