“…Rare-earth doped Y 2 SiO 5 have been used to demonstrate efficient quantum information storage [155] and operation at telecom wavelength [156]. Integration of such quantum memories onto a chip has been prototyped using the direct writing technique [157] and free-standing nanobeam waveguides [134] (see Figure 5e), resulting in frequency-encoded qubit storage with fidelity approaching 99% [158]. For a recent review of quantum memories, see Ref.…”

On-chip integration of quantum optical systems could be a major factor enabling photonic quantum technologies. Unlike the case of electronics, where the essential device is a transistor and the dominant material is silicon, the toolbox of elementary devices required for both classical and quantum photonic integrated circuits is vast. Therefore, many material platforms are being examined to host the future quantum photonic computers and network nodes. We discuss the pros and cons of several platforms for realizing various elementary devices, compare the current degrees of integration achieved in each platform and review several composite platform approaches.

“…Consequently, a series of simple and "low" retardance birefringent optical elements [12] were developed based on these porous nanolayers induced by ultrashort laser pulses in fused silica. Recent achievements include 5D optical recording [13], monolayer waveplates that act as azimuthal/radial polarization [14], optical vortex converters [15] but also waveguides retarders [16] and rotated waveplates in integrated waveguide optics [17].…”

Compact Birefringent Waveplates Photo-Induced in Silica by Femtosecond Laser

Recently, we showed that femtosecond laser induced "nanogratings" consist of thin regions with a low refractive index (Δn = −0.15), due to the formation of nanoporous silica surrounded by regions with a positive index change. In this paper, we investigate a wide range of laser parameters to achieve very high retardance within a single layer; as much as 350 nm at λ = 546 nm but also to minimize the competing losses. We show that the total retardance depends on the number of layers present and can be accumulated in the direction of laser propagation to values higher than 1600 nm. This opens the door to using these nanostructures as refined building blocks for novel optical elements based on strong retardance.

Integrated quantum photonics is now seen as one of the promising approaches to realize scalable quantum information systems. With optical waveguides based on silicon photonics technologies, we can realize quantum optical circuits with a higher degree of integration than with silica waveguides. In addition, thanks to the large nonlinearity observed in silicon nanophotonic waveguides, we can implement active components such as entangled photon sources on a chip. In this paper, we report recent progress in integrated quantum photonic circuits based on silicon photonics. We review our work on correlated and entangled photon-pair sources on silicon chips, using nanoscale silicon waveguides and silicon photonic crystal waveguides. We also describe an on-chip quantum buffer realized using the slow-light effect in a silicon photonic crystal waveguide. As an approach to combine the merits of different waveguide platforms, a hybrid quantum circuit that integrates a silicon-based photon-pair source and a silica-based arrayed waveguide grating is also presented.
