Quantum Co-packaged Optical Assembly

Packaging of QPICs requires low-loss coupling between fiber arrays and PICs. As QPICs typically operate on entangled or single photons, coupling is more critical than for conventional PICs, in which thousands of photons are manipulated at a time. In this paper we will report on the results from the UK government funded projects, in which a novel metallic aspherical micro-mirror array unit was coupled for the first time to a QPIC. The micro-mirror array is formed in a stamping process allowing it to be produced in high-volume and it can be deployed in diverse environments including high temperature or cryogenic environments.
