Outstanding features of our single photon detectors
Broad capability
From the visible wavelength range of 400 nm up to the NIR wavelength range of 2,000 nm, our detectors ensure high system detection efficiency without the need to change the module.
High scalability
Due to the waveguide-integrated approach, our technology is highly scalable. This means that hundreds of detectors can be implemented in one single system, consuming only a small amount of space.
Top efficiency
Due to our unique waveguide-integration approach, the internal quantum efficiency can be engineered to always be 100 % for any wavelength.
Timing resolution
Our detectors have an excellent timing resolution with timing jitter typically on the order of tens of picoseconds. Even jitter below 30 ps is possible.
Counting at high speed
Our detectors typically recover in less than 10 nanoseconds and therefore can reach very high count rates – even within the GHz range.
Photon number resolving
Soon, we will also realize photon number resolving detectors based on our waveguide-integrated SNSPDs. This adds another functionality and shows the versatility of our approach.
Numerous functionalities
Our unique approach allows us to exploit the full potential of integrated photonic devices by enabling e.g. filtering, splitting and phase shifting, therefore enabling application e.g. as a QKD receiver.
High signal to noise ratio
Distinguishing well between true photons and noise, our waveguide-integrated superconducting nanowire single photon detectors (WI-SNSPDs) offer very low dark count rates (typically less than 1 Hz) and a high signal-to-noise ratio.
