Abstract
An electronic receiver array for decoding data encoded into electromagnetic radiation (e.g., light) is described. The light is received at an ultra-small resonant structure. The resonant structure generates an electric field in response to the incident light and light received from a local oscillator. An electron beam passing near the resonant structure is altered on at least one characteristic as a result of the electric field. Data is encoded into the light by a characteristic that is seen in the electric field during resonance and therefore in the electron beam as it passes the electric field. Alterations in the electron beam are thus correlated to data values encoded into the light.
