Abstract
An optical antenna collects, modifies and emits energy at light wavelengths. Linear conductors sized to correspond to the light wavelengths are used. Nonlinear junctions of small dimension are used to rectify an alternating waveform induced upon the conductors by the lightwave electromagnetic energy. The optical antenna and junctions are effective to produce harmonic energy at light wavelengths. The linear conductors may be comprised of carbon nanotubes that are attached to a substrate material, which may then be connected to an electrical port.
Claims18
A lightwave electromagnetic antenna for the purpose of sending and receiving electromagnetic energy, said electromagnetic antenna having a linear conductor electrically connected to a substrate material, said linear conductor having an electrical length sized to respond to an electromagnetic light wavelength.
A lightwave electromagnetic device having a linear conductor attached to a junction, said linear conductor having an electrical length sized to respond to light wavelength energy, said junction having a non-linear electrical charge transfer characteristic.
A method of generating harmonic energy near light wavelengths comprising the steps of:
- exposing a conductor to an infrared, visible or ultraviolet electromagnetic light energy having an alternating waveform,
- inducing a current with said electromagnetic energy in said conductor to cause an electrical charge to cross a junction,
- emitting at least a portion of said energy at a harmonic multiple of said light energy from said junction.
A device for rectifying an alternating waveform occurring around light wavelengths comprising;
- a short conductor of less than 10,000 nanometers in length, and,
