Abstract
An electronic receiver for decoding data encoded into 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. 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.
