Title: SUBSTRATE DEFECT BASED DEMODULATION
Abstract:
Devices and methods for demodulating a frequency modulated electromagnetic wave are provided. In various embodiments, a device includes a substrate comprising at least a first region having a plurality of atomic defects therewithin. The device includes a light source configured to emit electromagnetic radiation of a first wavelength and to illuminate the first region of the substrate. The first region of the substrate emits electromagnetic radiation of a second wavelength when exposed to electromagnetic radiation of the first wavelength. The device includes a photodetector configured to detect electromagnetic radiation of the second wavelength. The photodetector is configured to detect electromagnetic radiation emitted by the first region of the substrate.
