Abstract:
A source of collimated light, in particular a source of single photons. The source comprises a cavity in the shape of an inverted pyramid formed in a substrate. At least one quantum dot (Bq) suitable for emitting light with a wavefront is arranged at the apex of the inverted pyramid and a structure ( 4 ) having an index gradient fills the cavity. This structure has an effective index that decreases from the centre of the base towards the sides. Thus, the wavefront of the light emitted by the at least one quantum dot is flattened. The invention extends to the method for manufacturing such a source, and to its use for the emission of a sequence of single photons.

Claim (Index 6):
The source of collimated light according to  claim 5 , wherein each level comprises a first layer and a second layer made from different materials, the relative thickness of the first and second layers of a level varying gradually from one level to another in the succession of the deposited levels.
