Diamond possesses remarkable physical and chemical properties, and in many ways is the ultimate engineering material. For example, it is transparent from the ultra-violet to infrared, has a high refractive index (n = 2.4), strong optical nonlinearity (Kerr and Raman) and a wide variety of light-emitting defects. These properties make diamond a highly desirable material for many applications, including those in quantum and nonlinear photonics, high power optics and optomechanics.

In my talk, I will review the advances in nanotechnology that have enabled fabrication of nanoscale optical devices and chip-scale systems in diamond [1, 2]. Using these approaches we were able to demonstrate high-Q factor diamond photonic crystal cavities [3], frequency combs [4], and Raman lasers [5]. In my talk, I will discuss our ongoing efforts aimed at realization of on-chip frequency combs operating in visible wavelength range. Another exciting application of diamond is in the field of quantum information science and technology. At the heart of these applications are diamond’s luminescent defects—color centers—and the nitrogen-vacancy (NV) and silicon-vacancy (SiV) color center in particular. These atomic systems in the solid-state possesses all the essential elements for quantum technology, including storage, logic, and communication of quantum information. Recent efforts aimed at coupling of NV [6] and SiV [7] color centers to photonic crystal cavities will be presented. Our ongoing efforts towards achieving strong spin-strain interaction between color centers embedded inside diamond NEMS [8,9] and optomechanical crystals [10] will also be reviewed.
