Patent ID: 7646991

Claim:
An optical transmitter comprising: a source of charged particles; a data input for receiving data to be transmitted; a first resonant structure configured to be excited by particles emitted from the source of charged particles and configured to emit electromagnetic radiation at a first predominant frequency representing the data to be transmitted; a communications medium for carrying the emitted electromagnetic radiation at the first predominant frequency, wherein the first predominant frequency has a frequency higher than that of a microwave frequency; a second resonant structure configured to be excited by particles emitted from the source of charged particles and configured to emit electromagnetic radiation at a second predominant frequency; and at least one deflector having a deflection control terminal for selectively exciting the first and second resonant structures by the particles emitted from the source of charged particles, wherein the communications medium is also configured to carry the emitted electromagnetic radiation at the second predominant frequency, and wherein the second predominant frequency has a frequency higher than that of a microwave frequency.
