Micro transfer printing SNSPDs towards a fully integrated quantum photonic platform

Micro-transfer printing (uTP) gives the possibility to combine components from different substrates onto one common carrier chip. While its highly parallel manner allows for exceptional throughput, the ability to pre-characterise the components, make it a good die only approach, with high yield. The goal of this work is to combine devices containing waveguide-integrated superconducting nanowire single-photon detectors (SNSPDs) fabricated on ultra low loss SiN photonics to enable quantum computing applications and quantum key distribution.
