The design of the fiber sensors can take advantage of one or several optical parameters of the guided light, such as intensity, phase, polarization, and wavelength., small, lightweight, resistant to high temperatures and pressure, electromagnetically passive, among others. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. Attenuation in fiber optics can come from its attenuation coefficient, absorption, scattering, and extrinsic effects.
