ABSTRACT:
A photon detector capable of detecting gigahertz frequency optical signals utilizes a layer of photonic material that is formed adjacent to the coil of an inductor. When a pulsed light source is applied to the layer of photonic material, the photonic material generates eddy currents that alter the magnetic flux of the inductor. The signals can then be detected by detecting the change in the magnetic flux.
