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 26):
A method of forming a low loss taper in a glass optical fiber comprising greater than 0.5 wt % chlorine in a core, the core having an initial mode field diameter MFD (at 1550 nm) and is being surrounded by a cladding, said method comprising the steps of:\n expanding the initial core MFD at 1550 nm by at least 3 microns by applying heat to said optical fiber for less than 60 seconds in cumulative duration, thereby diffusing chlorine from the core of the optical fiber into the cladding of the optical fiber; cleaving said optical fiber at a location where the MFD was expanded by at least 3 microns.
