The key goal of the proposed work is to combine quantum optics with integrated photonic circuits in order to take the first steps towards a new technology, i.e. Integrated Quantum Photonics (IQP). We want to incorporate the ultimate limit of a light source, i.e. an emitter which emits single quanta of light, photons, on demand onto microphotonic circuits. The circuits will take the form of a silicon chip exploiting most advanced nanofabrication technology. Optical elements such as waveguides, beam splitters (couplers), and filters will be designed and integrated on the chip. We will demonstrate key quantum optical functionalities on-chip such as two photon interference (Hong-Ou-Mandel effect), quantum electro-dynamical enhancement of photon emission (Purcell effect) and single photon logical operations (Dipole Induced transparency). With single photon sources (SPS) and optical elements for the first time integrated on a chip, we hope to pave the way for novel concepts in photonics at the ultimate level of minaturization as well as for a future integrated optical quantum technology.
