Abstract

A coated multipurpose optical fiber is provided. The optical fiber can be used as a delivery fiber (120) or as a coupling fiber (140, 145) for an optical data link with low coupling loss for silicon photonic lasers, VCSELs, single-mode delivery fibers, multimode delivery fibers and high-speed receivers . An optical fiber includes a core, an optional inner cladding region, a depressed index cladding region, an outer cladding region, and a coating. The relative index profile of the coupling fiber includes a small-radius core region with an α profile and a depressed-index cladding region that promotes low bend loss and high modal bandwidth. The coating thickness and overall diameter of the optical fiber are small.

Description

[0001] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application Serial No. 62 / 356,089, filed June 29, 2016, upon which this application is based and which is hereby incorporated by reference in its entirety . technical field [0002] This specification concerns optical fibers designed for efficient coupling to chips and devices used in silicon photonics. More specifically, the present specification relates to multifunctional optical fibers having low macrobending bend loss in tight bend configurations and efficient coupling to single-mode and multimode light sources, waveguides, other optical fibers, and optical fibers used in the transmission and reception of optical signals Detector. Most particularly, this specification relates to small diameter multipurpose optical fibers with coatings that minimize microbend losses. Background technique [0003] The need for greater bandwidth and higher data transfer rates has driven efforts to develop nex...
