Quantum light on demand
Cutting-edge photonic components, meticulously engineered to deliver on-demand, highly coherent emissions.
A scalable and efficient solution for quantum light generation
With over two decades of dedicated research at the Niels Bohr Institute in Copenhagen, we have achieved remarkable milestones in the field of nanophotonic design and fabrication. Our relentless pursuit of excellence has culminated in the creation of a world-class product: an on-chip, scalable, and deterministic single-photon source.
The planar design for our quantum emitter chip is absolutely unique: we can guide quantum light along the chip with near-unity efficiency. An ultra-low noise environment is achieved by applying a controlled electric field to trap the residual charges that typically deteriorate the emission coherence of the quantum dot. The combination of these features leads to the highest fidelity of single-photon generation available in the market.
How does is work?
For optimal use, our on-chip single-photon source must be mounted in a low-vibration cryostat with electrical and optical access.
The quantum dot is excited by a pulsed laser focused onto the chip containing the quantum dot emitter via a confocal microscope objective.
Single-photon emission is collected via the same objective, and the laser pump light is automatically filtered out thanks to the photonic crystal nanostructures.
The single-photon stream is then ready-to-use.
