Abstract
Photon emitter and data transmission device wherein a second resonator is arranged in a direction of emission of a radiation-emitting first resonator in such a way that a quantum dot contained in the second resonator can be excited by energy of radiation emitted by the first resonator. A control unit brings the excitation ground state of the quantum dot into resonance with a prescribed resonator mode of the second resonator.
Claims20
A single photon emitter comprising:
- a radiation-emitting first resonator;
- a second resonator, which is integrated with the first resonator and has a plurality of quantum dots;
- the second resonator arranged in a direction of emission of radiation emitted by the first resonator, wherein at least one quantum dot of the plurality of quantum dots in the second resonator is excited by energy of the emitted radiation;
- and
- a control unit coupled to the second resonator to set an excitation ground state of the at least one quantum dot of the plurality of quantum dots in the second resonator;
- wherein the excitation ground state of exactly one quantum dot of the plurality of quantum dots in the second resonator is brought into resonance with a prescribed resonator mode of the second resonator.
