Abstract:
1. An optical device comprising a plurality of layers, the optical device comprising: an optical fiber having a substantially axial symmetry, the optical fiber comprising a transparent envelope surrounding a core doped with phosphorescent or fluorescent material, said transparent envelope comprising a cladding layer; and a light source comprising an inner electrode layer, a reflective outer electrode layer, and an active area layer located between said inner electrode and said outer electrode, wherein said light source and said optical fiber are integrated, and wherein said light source has an axial symmetry and is positioned coaxially with respect to the axis of said optical fiber, and wherein said inner electrode comprises a transparent material to permit light generated in said active area to propagate outside said light source and into said optical fiber, wherein at least one of the layers has imperfections whereby the imperfections act to increase the optical coupling efficiency into the optical fiber.
