Abstract
An integrated optical device and method for generating photons by manipulating path entanglement is provided. An integrated optical splitter splits pump light between two interferometer arms wherein each arm comprises a substantially identical photon pair source configured to be able to convert at least one pump light photon into a signal and idler photon pair. An integrated optical combiner device in optical communication with a first and a second optical output path interferes light from the first and second arms and outputs the signal and idler photons by bunching the signal and idler photons together in one of the optical output paths, or anti-bunching the signal photon in one output path and the corresponding idler photon in the other optical output path.
