Abstract: The present invention is directed to an optical fiber that includes a glass core region that has nano-sized structures configured to scatter light propagating in the glass core region. The glass core region has an average refractive index navg. The fiber includes an interior glass cladding region that has an interior cladding refractive index n2 that is less than navg. The fiber includes an outer cladding region that has an outer cladding refractive index n3 that is less than n2. A refractive index difference of n2−n3 corresponds to a bend uniformity diameter; the light exiting the outer cladding at a fiber bending location is substantially non-uniform when a bending diameter of the fiber bending location is less than the bend uniformity diameter.

Abstract: The high-density FAU comprises a support substrate having a grooved front-end section that supports glass end sections of the small diameter low-attenuation optical fibers. A cover is disposed on the front-end section and secured thereto to hold the glass end sections in place. The substrate and the cover can be made of the same glass or glasses having about the same CTE. The glass end sections have a diameter d4 so that the pitch P2 of the fibers at the front end of the FAU can be equal to or greater than d4, wherein d4=2r4, with r4 being the radius of the glass end section as defined by the optical fiber cladding. The glass end section has a radius r4 less than 45 microns, allowing for a high-density FAU and a high-density optical interconnection device.
