Abstract
Systems and methods for performing wavelength conversion via plasmon-coupled surface states are described that can be used for optical wavelength conversion to different parts of the electromagnetic spectrum ranging from microwave to infrared regimes in both pulsed and continuous wave operation.
Claims19
A wavelength conversion device comprising:
- at least one semiconductor substrate;
- and
- at least one conductive layer;
- wherein the semiconductor substrate comprises at least one region that has a built-in electric field;
- wherein the conductive layer comprises at least one electrode with at least one optical subwavelength dimension;
- and
- wherein the at least one electrode is capable of bending incident optical light to couple with the at least one region that has the built-in electric field to convert the optical wavelength to a different wavelength of the electromagnetic spectrum.
