Abstract

The creation of a quantum photonic integrated circuit, bringing together quantum light sources; detectors; and elements for routing and modulating the photons; is a fundamental step towards a compact and self-contained quantum information processor. Here we report on the realisation of a new hybrid integration platform for InAs Quantum Dot-based quantum light sources and waveguide-based photonic circuits. In this scheme, GaAs devices containing embedded quantum dots are bonded to a silicon oxynitride waveguide circuit such that the quantum dot emission is coupled to the waveguide mode. The output from the waveguide element is coupled into optical fibre (also bonded to the waveguide chip) and the whole assembly is cooled to cryogenic temperatures. Integrated tuneable Mach-Zehnder interferometers permit on-chip photon routing to be achieved and allow the device to act as a path-encoded qubit preparation device. By utilising one such interferometer as a reconfigurable beam splitter, the single photon nature of the emission was confirmed by a Hanbury Brown and Twiss measurement on chip.
