Coupled Power Analysis for Hybrid Optical Fibers

This paper brings a short view into the hybrid communication-sensing fiber analysis. Common communication fibers can not be used as a sensor for many reasons. And, on the other hand, fibers used as sensors can not be used for communication purposes. It is necessary to propose a hybrid fiber, which preserves character of the standard communication fiber but which makes it possible to do some measurement. These fibers use two wavelengths, one for communication purposes and one for use as an optical sensor. Output on the sensing wavelength is processed using the coupled power equations.
