Smith, Brian J., Kundys, Dmytro, Thomas-Peter, Nicholas, Smith, P.G.R. and Wamsley, I.A. (2009) Phase-controlled integrated photonic quantum circuits. Optics Express, 17, (16), 13516-13525. (doi:10.1364/OE.17.013516).
Scalable photonic quantum technologies are based on multiple nested interferometers. To realize this architecture, integrated optical structures are needed to ensure stable, controllable, and repeatable operation. Here we show a key proof-of-principle demonstration of an externally controlled photonic quantum circuit based upon UV-written waveguide technology. In particular, we present non-classical interference of photon pairs in a Mach-Zehnder interferometer constructed with X couplers in an integrated optical circuit with a thermo-optic phase shifter in one of the interferometer arms.
