Abstract
An extrinsic optical waveguide sensor for making refractive index measurements of an in situ sample is provided. The sensor comprises a holder having at least one sample input region and at least one interferometric region. At least one optical fiber is positioned in the holder, each optical fiber having an endface serving as an input and an output. At least one reflector, each reflector is positioned in the holder in an operable relationship to each optical fiber endface, thus defining each interferometric region.
