Abstract

A multi-purpose optical fiber with coating is provided. The optical fiber can function as a transmission fiber or as a coupling fiber for optical data links that features low coupling loss to silicon photonics lasers, VCSELs, single mode transmission fibers, multimode transmission fibers, and high speed receivers. The fiber includes a core, an optional inner cladding region, a depressed index cladding region, an outer cladding region, and a coating. The relative refractive index profile of the coupling fiber includes a small-radius core region with α profile and a depressed index cladding region that facilitates low bending loss and high bandwidth. The coating thickness and overall diameter of the fiber is small.
