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.

Claim (Index 15):
A method of fabrication of a guided light source, comprising:\n forming a discoid wave guide, an annular wave guide surrounding the discoid wave guide and an output wave guide optically coupled to the annular wave guide; positioning at least one quantum box with respect to the discoid wave guide to achieve cylindrical propagation of a wave front emitted by the at least one quantum box in the discoid wave guide; and forming a grating coupler on an internal periphery of the annular wave guide to receive said wave front in normal incidence.
