Abstract
This paper reports the development of a hydrazine fiber optic reversible sensor that operates, for the first time to our knowledge, in the lowest attenuation wavelength range of commercial silica fibers. A pentacenediquinone (PDQ) and polymer mix, with an index of refraction adjusted to closely match that of silica, was used as an active sensing material replacing the cladding of a silica core optical fiber. The optical signal passing through this modified cladding type fiber sensor exhibited a reversible intensity change in the presence hydrazine at different concentrations.
