“…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].…”

“…CROW-based filters (Fig. 10c) have been reported to achieve 100 dB extinction [111]. The combination of corrugated-waveguide Bragg reflectors and ring resonators have enabled a correlation measurement of photon pairs entirely without further external filtering [51] (the pump transmission spectrum of this device is plotted in 10b).…”

Integrated quantum photonic applications, providing physially guaranteed communications security, sub-shot-noise measurement, and tremendous computational power, are nearly within technological reach. Silicon as a technology platform has proven formibable in establishing the micro-electornics revoltution, and it might do so again in the quantum technology revolution. Silicon has has taken photonics by storm, with its promise of scalable manufacture, integration, and compatibility with CMOS microelectronics. These same properties, and a few others, motivate its use for large-scale quantum optics as well. In this article we provide context to the development of quantum optics in silicon. We review the development of the various components which constitute integrated quantum photonic systems, and we identify the challenges which must be faced and their potential solutions for silicon quantum photonics to make quantum technology a reality

“…Thermal [14], [15], electrical [16] or optical tuning technologies can be exploited to dynamically select a proper set of wavelengths for different switching speeds. Optimizing the design of MRRs becomes fundamental to develop MRR switching devices characterized by very narrow or very wide flat-top passband widths.…”

The physical characteristics of microring resonator switching devices are thoroughly analyzed using a model based on the field coupling matrix theory. The spectral response and insertion loss properties of these switching elements are simulated using the developed model. Results show that by cascading three microring resonators it is possible to achieve flat-top passband widths ranging from 6.25 GHz to 3 THz, while having insertion losses compatible with the use in flexible-grid optical communication networks. In light of a potential use of these devices in the design of a scalable flexible wavelength selective switch, the architecture of simple optical switches with limited functionalities is discussed.
