Nonlinear optics and single photon detection on a chip
Superconducting nanowires for recording single photon events in a chip.
POSTPONED TO A LATER DATE!
Nanophotonic devices allow for realizing complex optical functionality that is otherwise difficult to achieve with free-space optical setups. While such circuits find a multitude of applications in telecommunication and integrated optics, their tremendous potential for non-classical optics and quantum computation remains largely unexplored. Here I will present an integrated platform in which key challenges of integrated quantum optics are addressed by implementing nonlinear optical devices in combination with nanostructured superconducting thin films.
Superconducting nanowires are particularly promising for recording single photon events in a chip-scale framework. Besides offering near-perfect detection efficiency, they also provide a small footprint and scalability as a key step towards integrated quantum optical circuits.
Working with a nonlinear optical substrate material furthermore enables active control of photon interaction. Leveraging additional degrees of freedom provided by free-standing mechanical structures thus yields a rich architecture for studying fundamental physics and emerging applications in chip-based metrology.
