System and method for plasmonic control of short pulses in optical fibers

An optical waveguide system including:

• a first waveguide having a core-guide and a cladding material portion surrounding and encasing the core-guide to form a substantially D-shaped cross sectional profile with an exposed flat section running along a length thereof, the core-guide enabling a core-guide mode for an optical pulse signal having a first characteristic, travelling through the core-guide;
• a material layer of non-linear material forming a second waveguide, the material layer being disposed on the exposed flat section of the cladding material portion, the material layer forming a plasmonic device to achieve a desired coupling with the core-guide to couple optical energy travelling through the core-guide into the material layer, which modifies the optical energy travelling through the core-guide to cause the optical energy travelling through the core-guide to have a second characteristic different from the first characteristic;
• and
• an additional plasmonic device forming a lattice like structure having a plurality of spaced apart strips held in an arrangement with a fixed spacing, the additional plasmonic device being disposed on a surface of the material layer.

A surface emitting optical fiber including:

• an optical fiber having a core-guide and a cladding material portion surrounding and encasing the core-guide, the core-guide forming a first wave-guide and enabling a core-guide mode for an optical signal having a first pulse profile travelling through the core-guide;
• a second waveguide secured to an outer surface of the first waveguide, the second waveguide forming a plasmonic device which implements a plasmonic mode waveguide;
• the construction of the second waveguide being such as to achieve a desired level of coupling between the core-guide mode and the plasmonic mode waveguide such that optical energy coupled into the second waveguide has a second pulse profile being different from the first pulse profile, which is emitted out from the second waveguide;
• a plurality of the second waveguides disposed along a length of the cladding material portion and spaced apart from one another;
• and
• wherein the cladding material portion is arranged in a coil, and ones of the plurality of second waveguides are arranged to be aligned along the coil.
