Diamond possesses remarkable physical and chemical properties, and in many ways is the ultimate optical engineering material, but its use until relatively recently has been limited by the lack of scalable techniques for manufacture, processing and integration. This paper will review and summarize key progress in fabrication techniques utilizing chemical vapour deposition (CVD), processing using mechanical and chemical methods and solutions for integration. It will present several case studies that include polycrystalline diamond for high power CO2 optics for applications that include EUV to manipulation of optical signals at single-photon level in single crystal CVD diamond using nano-cavities and waveguides.
