Patent ID: 7043127

Claim:
An optical connecting component comprising a microstructured optical fiber, a non-microstructured optical fiber, and a fixing means, wherein the microstructured optical fiber comprises a core, and a cladding surrounding the core, the cladding comprising a main medium having refractive index n1 at a predetermined wavelength λ between 200 nm and 1700 nm, and a plurality of sub medium regions arranged in the main medium, the sub medium having a refractive index n2 at the wavelength λ; the non-microstructured optical fiber comprises a core having a refractive index N3 at the wavelength λ, and a cladding surrounding the core and having a refractive index N4, lower than N3, at the wavelength λ; a first end of the non-microstructured optical fiber has a polished interface surface; a second end of the non-microstructured optical fiber is spliced to a first end of the microstructured optical fiber; and the polished interface surface, the non-microstructured optical fiber and the first end of the microstructured optical fiber are fixed to the fixing means.
