Abstract
An optical fiber sensing cable is disclosed. The optical fiber sensing cable comprises a fiber with a core having an index of refraction n1, and a circumferential surface of the fiber including a nanoporous cladding having an index of refraction index n2. The methods of preparing the fiber sensor cable, including forming the nanoporous cladding and the sensor systems incorporating the optical fiber sensing cable of this invention are also disclosed.
