Abstract

The present disclosure relates to a non-invasive and real-time diagnostic analysis concept for a working single-mode fiber optic communication system and a method of using the same. The system includes optical fibers capable of being non-invasively diagnosed, including optical fibers for delivering light beams. The optical fiber includes a first end for receiving a light beam and a second end opposite thereto, a core including an inner wall and a cladding around the core, the optical fiber further includes at least one cladding-free portion comprising a plurality of quantum dots dispersed in a medium, and wherein the quantum dots become activated by evanescent wave coupling caused by total internal reflection of a light beam contacting the inner wall of the core of the optical fiber, and wherein the activation results in light Emission from quantum dots.

Description

technical field [0001] The present disclosure relates generally to optical fibers, and more particularly to non-invasive sensing mechanisms for real-time diagnostic analysis of working optical fibers. Background technique [0002] While fiber optic transmission systems have many advantages, they also have some problematic aspects. For example, (1) transmitter power is subject to high manufacturing tolerances; (2) transmitter power decreases over time (from just detectable to very strong, depending on wavelength); (3) optical fibers made of plastic age very fast, especially when exposed to strong temperature fluctuations; (4) by frequently changing the plug, the contact surface of the fiber is scratched, which additionally increases attenuation; and (5) the sensitivity of the receiver is also subjected to high manufacturing tolerances. One of the worst problems is presented by aging and reduced transmitter power. A failure of a fiber optic link, eg due to high attenuation ...
