  Fundamental to integrated photonic quantum computing is an on-chip method for
routing and modulating quantum light emission. We demonstrate a hybrid
integration platform consisting of arbitrarily designed waveguide circuits and
single photon sources. InAs quantum dots (QD) embedded in GaAs are bonded to an
SiON waveguide chip such that the QD emission is coupled to the waveguide mode.
The waveguides are SiON core embedded in a SiO2 cladding. A tuneable Mach
Zehnder modulates the emission between two output ports and can act as a
path-encoded qubit preparation device. The single photon nature of the emission
was verified by an on-chip Hanbury Brown and Twiss measurement.
