In a general aspect, a system includes a plurality of diamond nanowires disposed on the surface of a diamond substrate, at least some of the nanowires including a color center. The system also includes a light source configured to illuminate at least one of the plurality of nanowires with excitation light at a wavelength corresponding to an excitation wavelength of the color center included in the illuminated nanowire; and an optical receiver configured to receive a fluorescence emitted from the color center included in the illuminated nanowire in response to the excitation light.

A system for efficient generation of THz radiation is provided that includes a triply-resonant nonlinear photonic resonator coupled to at least one near-infrared (NIR) or optical waveguide and to at least one THz waveguide. The energy traveling through the at least one near-infrared (NIR) or optical waveguide is converted to THz radiation inside the triply-resonant photonic resonator via a nonlinear difference frequency generation (DFG) process.
