Quantum photonics

Photonic integrated circuits possess great potential in replacing electronics in next-generation computation and signal processing. Particularly, by combining integrated photonics and quantum technologies, quantum protocols that otherwise require bulky free-space optics and/or cryogenic operation conditions can be implemented in a compact and power-efficient fashion. We develop devices that serve as building blocks in a photonic quantum circuit, such as beam splitters and polarization converters. Not only do we aim at devices of great performance, but we also address novel design principles inspired by quantum physics, such as level anti-crossing and atomic physics phenomena such as stimulated Raman adiabatic passage (STIRAP).
