    Abstract: A fiber Bragg grating cross-wire sensor may be used to independently determine strain and temperature variation. An example fiber Bragg grating cross-wire sensor comprises a first fiber Bragg grating (FBG) that reflects a first percentage, R 1 , of light of a first wavelength, λ 1 , and a second FBG that reflects a second percentage, R2, of light of a second wavelength, λ 2 . The second FBG is positioned orthogonal to the first FBG, and λ 1 is substantially equal to λ 2 , but R 1 is different from R 2 . As the FBG cross- wire sensor experiences a strain and/or a temperature variation, the wavelengths of light reflected by the first FBG and the second FBG will shift from the first and second wavelength, λ 1 and λ 2 , to first and second shifted wavelengths, λ A and λ T , respectively. Based on R 1 R 2 , λ 1 , λ A , and XT, the strain and/or the temperature variation may be independently determined..

    Abstract: An optical fiber system that includes an in-fiber optic component powered by in-fiber light includes an optical fiber having a core, wherein the optical fiber propagates a sensing/signal light and a power light, with the sensing/signal light being propagated in the core. An optical transducing element, such as a layer of light absorbing material, is located in proximity to the in-fiber optic component. An optical tap region is provided in the optical fiber in proximity to the optical transducing element, and enables the power light to leak from the optical fiber and be absorbed by the optical transducing element. The optical transducing element converts the absorbed power light into a second energy form, such as heat, which is used to tune the in-fiber optic component.
