Paper Abstract

Monolithic photonics architectures which enable the generation and processing of quantum states of light will be discussed. Some architectures are shown to exhibit characteristics that are unique to integrated architectures over their bulk-optics counterparts. If we use on-chip quantum interference as an example, one find it is often assumed that the 2x2 mode coupler maintains a 50:50 splitting ratio over the twin-photons’ entire joint spectrum. However, this is not necessarily the only case possible for integrated devices. For some designs the interferometer behaves as an ideal 50:50 beamsplitter (BS), while for others it behaves as an ideal wavelength de-multiplexer (WD). This interesting ramifications for two-photon interference, where dispersion can allow integrated 2x2 couplers to play a far more versatile role in quantum circuits than their bulk-optics counterparts.
