Sparrows high-quality source for single photons on demand

Explore the Sparrow Quantum single-photon chip, combining strain-induced InAs/GaAs quantum emitters with nanoengineered photonic structures to emit highly coherent single photons

How does it work?

For optimal use, the chip must be mounted in a low-vibration cryostat with electrical and optical access.
The quantum dot is excited by a pulsed laser which is 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 hence ready-to-use.

A scalable and efficient solution for quantum light generation

With over two decades of dedicated research, 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 >90% 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.
