Generation of strongly sub-Poissonian light from a coherent input using a waveguide network with engineered nonlinear loss. The two top (magenta) waveguides are the signal modes, that are coupled only through the reservoir, which is realised as an array of evanescently coupled waveguides (blue).
We refer to the linear arrangement of waveguides (blue) implementing a common bath as "tail". The waveguides are laser inscribed in a bulk glass with high third order nonlinearity.
Phase space insets show contours of the Wigner function of coherent states (left, input) and photon number squeezed states (right, output).

PhoG - Sub-Poissonian Photon Gun by Coherent Diffusive Photonics
EU Flagship Quantum Technologies project
The goal of the project is to deliver deterministic and compact sources of highly non-classical states, from sub-Poissonian light to multi-mode entanglement, all using a single technological platform. The consortium PhoG will build working prototypes and develop the technological foundation for the applications of these sources in advanced optical imaging and metrology.
The proposed sources will be based on a novel paradigm in photonic devices: coherent diffusive photonics operating with dissipatively coupled optical waveguides. The project will demonstrate that light can flow diffusively while retaining coherence and even entanglement, can be effectively equalized and distributed in a controlled way by means of dissipative coupling. Such unique light propagation regimes will be realized with the help of a photonic analogue of a tight-binding lattice using coupled waveguide networks in linear and non-linear glass materials. The decisive role is played by the linear and nonlinear engineered loss. These coherent photonic devices will be fabricated by ultrafast laser inscription. The dissipative coupling will be realised by coupling each pair of the waveguides carrying optical signal to a linear chain of waveguides that act as a dissipative reservoir. Efficient quantum diagnostic methods will be developed to verify the source characteristics and to assess their technological readiness. We expect coherent diffusive photonic devices to find applications in photonic networks and in a range of metrology tasks, potentially also for simulations of complex quantum dynamics. The specific project goals are:
(1) to implement a family of compact sub-Poissonian photon guns, capable of robust generation of mesoscopic non-classical and entangled states at 1550 nm and at 852/894 nm; (2) to perform a feasibility study of their applications in entanglement-enhanced imaging and atomic clocks aiming at the 2-4 times better clock frequency stability.
