Multimode quantum interference of photons in multiport integrated devices
arXiv:1007.1372 · doi:10.1038/ncomms1228
Abstract
We report the first demonstration of quantum interference in multimode interference (MMI) devices and a new complete characterization technique that can be applied to any photonic device that removes the need for phase stable measurements. MMI devices provide a compact and robust realization of NxM optical circuits, which will dramatically reduce the complexity and increase the functionality of future generations of quantum photonic circuits.
