Title:
MULTICORE OPTICAL FIBER APPARATUS, METHODS, AND APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2015/163963
Kind Code:
A3
Abstract:
Fiber optic sensors based on multicore optical fibers that are intended for use in harsh environment sensing. This multicore fiber comprises an arrangement of optically coupled cores in a silica background. Sensors are fabricated by splicing a section of multicore fiber between two single mode fibers. This multicore fiber sensor is simple and repeatable to fabricate and multiple sensors can be multiplexed in a chain. These fiber optic sensors are intended for a broad set of sensing applications including temperature, pressure, strain, bending, acoustic vibrations, mechanical vibrations, or combinations thereof.
