First Claim
1. An illumination system comprising:
- a light-diffusing optical fiber comprising a first input end and a second input end, the light-diffusing optical fiber having a glass core, a cladding surrounding the glass core, and an outer surface, and further comprising a plurality of nano-sized structures situated within the fiber, the nano-sized structures being configured to scatter light;
a first light source optically coupled to the first input end of the light-diffusing optical fiber and configured to generate light having a first wavelength, wherein an intensity of light emitted from the first light source is adjustable; and
a second light source optically coupled to the second input end of the light-diffusing optical fiber and configured to generate light having a second wavelength, wherein an intensity of light emitted from the second light source is adjustable;
wherein a color variation forms within the light-diffusing optical fiber at a junction of the light emitted from the first light source and the light emitted from the second light source;
wherein the location of the color variation is adjustable along the light-diffusing optical fiber by adjusting intensity of light emitted from one or more of the first light source and the second light source.

Abstract
An illumination system configured to produce color movement along the length of an optical fiber. The system can include a light-diffusing optical fiber having a first input end and a second input end, a glass core, a cladding surrounding the glass core, and an outer surface. Nano-sized structures are situated within the glass core or at the core-cladding boundary in order to scatter light. A first light source is optically coupled to the first input end, and a second light source is optically coupled to the second input end. A color variation forms within the optical fiber at the junction of the light emitted from each end of the fiber, and adjusting the intensity of light emitted from one or more of the first light source and the second light source causes the location of the color variation to move along the length of the optical fiber.
