Fiber-Tip Fabry-Perot Interferometric Sensor based on a Thin Silver Film

Abstract

Fiber-optic sensors can be used to measure a wide range of physical parameters, such as strain, temperature, pressure and other quantities by recording the changes in light intensity, phase, polarization or wavelength caused by these parameters in the fiber1-6. Compared to their electronic counterparts, fiber-optic sensors can provide numerous advantages. They are electromagnetically passive and immune to electromagnetic interference, which make them suitable for operation in environments with high and variable electric field 3. They are made from silica glass so they are chemically and biologically inert. Also, the small size of optical fibers, generally on the order of hundreds of micrometers in diameter, makes the fiber-optic sensors physically small and light in weight. They can also perform distributed measurement, in which the measurand can be determined as a function of position along the length of a fiber or at a number of pre-selected locations of the fiber.
