Nanodiamond Integration with Photonic Devices

Abstract

The progress in integration of nanodiamond with photonic devices is analyzed in the light of quantum optical applications. Nanodiamonds host a variety of optically active defects, called color centers, which provide rich ground for photonic engineering. Theoretical introduction describing light and matter interaction between optical modes and a quantum emitter is presented, including the role of the Debye-Waller factor typical of color center emission. The synthesis of diamond nanoparticles is discussed in an overview of methods leading to experimentally realized hybrid platforms of nanodiamond with gallium phosphide, silicon dioxide, and silicon carbide. The trade-offs in the substrate index of refraction values are reviewed in the context of the achieved strength of light and matter interaction. Thereby, the recent results on the growth of color center-rich nanodiamond on prefabricated silicon carbide microdisk resonators are presented. These hybrid devices achieve up to fivefold enhancement of the diamond color-center light emission and can be employed in integrated quantum photonics.

Universal programmable photonic architecture for quantum information processing

“…While this work is purely theoretical, there has been tremendous recent experimental progress in both of the key technologies required to realize this device: programmable photonic processors [4, 8-11, 16, 58-60] and strongly coupled quantum emitters [23][24][25][26][27][28][29]43]. The ongoing advancements in these technologies may allow for feasible near-future implementation of the device described in this paper.…”

“…This is accomplished by nonlinear interactions between two photons scattering off of a pair of quantum emitters embedded within the waveguides. The emitters could be implemented by quantum dots coupled to photonic crystal waveguides [23][24][25] or plasmonic nanowires [26], diamond vacancy centers [27][28][29], or many other experimental setups. The scattering dynamics discussed in this section are based on the scheme described by Zheng et al [30], with the notable difference that spatial modes rather than momentum states form the computational basis for the physical qubits.…”

“…This allows surface functionalization, allowing the formation of electrostatic [4][5][6] or covalent linkages, and facilitating the preparation of hybrid organic-nanodiamond materials [7,8]. This has greatly contributed to a widespread application of these organic-nanodiamond carbon materials [9][10][11][12][13][14], in biomedicine [15][16][17][18], nonlinear optical materials [19,20], energy devices [21,22] and tribology [23,24].…”
