Abstract:
A guided light source that comprises: at least one quantum box associated with a discoid wave guide to achieve cylindrical propagation of a wave front emitted by the at least one quantum box in the discoid wave guide; an annular wave guide surrounding the discoid wave guide and having a grating coupler formed on its internal periphery to receive the wave front in normal incidence; an output wave guide optically coupled to the annular wave guide, in which the wave front is guided. The invention includes the method of fabrication of such a source, and its use for emission of a sequence of single photons.
