How does it
work?

The chip is made from ultra-precise InAs/GaAs quantum dot structures embedded in photonic crystal waveguides.

The 3mmx3mm chip is sectioned into an array of structures engineered for emitting single photons at specific wavelengths ranging between 920nm to 980nm.

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.
