“…However, for scalable integration into quantum optics circuits, two challenges must be solved: the on-chip rejection of the pump field and spectral demultiplexing. In particular, and despite very recent attempts [9,10], the filtering of the pump field, which requires an extinction on the order of approximately 100 dB, has never been achieved without using off-chip filters.…”

We demonstrate the generation of quantum-correlated photon pairs combined with the spectral filtering of the pump field by more than 95 dB on a single silicon chip using electrically tunable ring resonators and passive Bragg reflectors. Moreover, we perform the demultiplexing and routing of signal and idler photons after transferring them via an optical fiber to a second identical chip. Nonclassical two-photon temporal correlations with a coincidence-to-accidental ratio of 50 are measured without further off-chip filtering. Our system, fabricated with high yield and reproducibility in a CMOS-compatible process, paves the way toward large-scale quantum photonic circuits by allowing sources and detectors of single photons to be integrated on the same chip.

“…One such example is the popular sidewall Bragg grating that offers a simple technological geometry to design TE polarisation filters with apodised and chirped profiles [10][11][12]. The strong polarisation scattering limits the maximum extinction ratio (ER) of these filters to approximately 30 dB [10], which prevents their exploitation in applications requiring a high ER such as quantum circuits [13][14][15]. Filters with higher ER values can be obtained with more complex designs such as Bragg gratings integrated with Mach-Zehnder interferometers [16] or coupled ring resonators [15,17].…”

“…Demonstrations of structures that enhance photon generation rates via SFWM include rectangular waveguides [50,[77][78][79], and microring resonators [38,41,43,[80][81][82][83][84][85][86][87][88]; see Figure 5D-F. As SFWM involves the annihilation of two photons, pair generation rates scale with the square of the optical intensity. With standard single-mode waveguide geometries of 500 nm by 220 nm, optical intensities in integrated structures are enhanced by the inverse of the effective mode area [70] with respect to bulk-silicon SFWM pair sources.…”

Quantum information science offers inherently more powerful methods for communication, computation, and precision measurement that take advantage of quantum superposition and entanglement. In recent years, theoretical and experimental advances in quantum computing and simulation with photons have spurred great interest in developing large photonic entangled states that challenge today's classical computers. As experiments have increased in complexity, there has been an increasing need to transition bulk optics experiments to integrated photonics platforms to control more spatial modes with higher fidelity and phase stability. The silicon-on-insulator (SOI) nanophotonics platform offers new possibilities for quantum optics, including the integration of bright, nonclassical light sources, based on the large third-order nonlinearity (χ (3) ) of silicon, alongside quantum state manipulation circuits with thousands of optical elements, all on a single phase-stable chip. How large do these photonic systems need to be? Recent theoretical work on Boson Sampling suggests that even the problem of sampling from ~30 identical photons, having passed through an interferometer of hundreds of modes, becomes challenging for classical computers. While experiments of this size are still challenging, the SOI platform has the required component density to enable low-loss and programmable interferometers for manipulating hundreds of spatial modes.Here, we discuss the SOI nanophotonics platform for quantum photonic circuits with hundreds-to-thousands of optical elements and the associated challenges. We compare SOI to competing technologies in terms of requirements for quantum optical systems. We review recent results on large-scale quantum state evolution circuits and strategies for realizing high-fidelity heralded gates with imperfect, practical systems. Next, we review recent results on silicon photonics-based photonpair sources and device architectures, and we discuss a path towards large-scale source integration. Finally, we review monolithic integration strategies for single-photon detectors and their essential role in on-chip feed forward operations.
