TITLE:

OPTICAL FIBER SENSORS WITH DOUBLE METALLIC LAYER ON THE FIBER END FACET AND WITH HETEROCORE STRUCTURES. 

 

KEY WORDS:

Sensors, corrosion, refractive index, metallic bilayer, heterocore optical fiber, cascade.

SUMMARY:

The present work addresses the development of two optical fiber-based sensor devices, one to monitor corrosion using a structure with a double metallic layer on the fiber end facet, the other to detect refractive index variations using a cascade of devices based on a fiber optic structures, the heterocore fiber, which work independently, and are interrogated at different wavelengths. The development of optical sensors for detecting corrosion and refractive index has increased considerably in the last years, and fiber optic sensors are ideal for extremely adverse conditions such as corrosion, temperature, pressure, humidity, among others. These advantages make fiber-optic-based sensors ideal for use in large structures such as the oil and gas industry, as well as many other applications. We performed the characterization of the devices through computational simulations, which are compared with experimental results. We performed the experimental characterization of the two sensor devices. The obtainedresults showed that the proposed devices are efficient to detect corrosion and refractive index.
