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.

Abstract: A fiber to waveguide coupler is provided that includes an optical fiber having a core and a cladding. The cladding includes an inner cladding and an outer cladding with a polymer. At least one of the core and inner cladding defines a substantially flat surface parallel with an axis of the optical fiber. The optical fiber defines a stripped portion substantially free of outer cladding configured to expose the at least one substantially flat surface of the core or inner cladding. A waveguide is configured to be evanescently coupled with the exposed at least one substantially flat surface of the core or inner cladding.
