Abstract
The present invention relates to a single photon sourcecomprising a tapered nanowire, where the nanowireis made of a semiconductor material, a first electrodeand second electrode, where the electrodes are electrically coupled to a photon emitterembedded in the nanowireand wherein the photon emitteris capable of emitting a single photon when an activation voltage is applied between the electrodes. In advantageous embodiments of the invention, the nanowire is encircled by air or vacuum, such that advantage can be taken of the resultant large ratio between a refractive index of the nanowire and the encircling material, air. Another advantageous feature might be that the first and second electrodes are optically transparent, such that they can be used as part of a reflective element or anti-reflective element.
