Abstract
We review recent experimental and theoretical results, which highlight the strong interest of the photonic wire
(PW) geometry for quantum optics experiments with solid-state emitters, and for quantum optoelectronic
devices. By studying single InAs QDs embedded within single-mode cylindrical GaAs PW, we have noticeably
observed a very strong (16 fold) inhibition of their spontaneous emission rate in the thin-wire limit, and a nearly
perfect funnelling of their spontaneous emission into the guided mode for larger PWs. We present a novel single
-photon-source based on the emission of a quantum dot embedded in an engineered PW, comprising a tapered tip
so as to control the radiation pattern, and an integrated hybrid bottom mirror. Unlike microcavity-based devices,
this source displays for the first time simultaneously a record-high efficiency (0.73 photon per pulse) and a very
low g(2) parameter. Numerical simulations show that an efficiency higher than 0.9 can be obtained for optimized
structures, under either optical or electrical pumping.
