Abstract:
An optical fiber for efficient coupling of optical signals to photonic devices. The optical fiber includes a Cl doped tapered core region with a changing outer diameter and changing maximum core refractive index to provide improved coupling at wavelength of interest to photonic devices. The photonic devices may be, for example, silicon photonic devices with an operating wavelength at or near 1310 nm, or at or near 1550 nm.

Claim (Index 33):
A system comprising:\n a silicon photonic device optically coupled to an optical fiber, said optical fiber comprising:\n a Cl doped silica based tapered core region, the tapered core region having an outer diameter Dc that changes along the length L 2  of the tapered core region and a maximum outer diameter D max  such that 8 microns\u2264D max \u226470 microns; the tapered core region further comprising a maximum core refractive index \u0394c that decreases along the length L 2  of the tapered core region; \n and a silica based cladding surrounding the core region.
