Solid-state single-photon emitters
631 Photonic technologies are becoming increasingly prevalent in our daily lives. After decades of rapid advances, light sources — especially lasers and light-emitting diodes — have become high-performance, yet low-cost and reliable components, driving the Internet and lighting cities. A new frontier of research is the development of non-classical light sources: sources that produce streams of ...
متن کاملNon-blinking single-photon emitters in silica
Samples for single-emitter spectroscopy are usually prepared by spin-coating a dilute solution of emitters on a microscope cover slip of silicate based glass (such as quartz). Here, we show that both borosilicate glass and quartz contain intrinsic defect colour centres that fluoresce when excited at 532 nm. In a microscope image the defect emission is indistinguishable from spin-coated emitters...
متن کاملSingle photon emitters in exfoliated WSe2 structures.
Crystal structure imperfections in solids often act as efficient carrier trapping centres, which, when suitably isolated, act as sources of single photon emission. The best known examples of such attractive imperfections are well-width or composition fluctuations in semiconductor heterostructures (resulting in the formation of quantum dots) and coloured centres in wide-bandgap materials such as...
متن کاملPhoton Sorters and QND Detectors Using Single Photon Emitters
We discuss a new method for realizing number-resolving and non-demolition photo detectors by strong coupling of light to individual single photon emitters, which act as strong optical nonlinearities. As a specific application we show how these elements can be integrated into an error-proof Bell state analyzer, whose efficiency exceeds the best possible performance with linear optics even for a ...
متن کاملModal Coupling of Single Photon Emitters Within Nanofiber Waveguides
Nanoscale generation of individual photons in confined geometries is an exciting research field aiming at exploiting localized electromagnetic fields for light manipulation. One of the outstanding challenges of photonic systems combining emitters with nanostructured media is the selective channelling of photons emitted by embedded sources into specific optical modes and their transport at dista...
