Tīmeklis1998. gada 4. aug. · ABSTRACT. Waveguide evanescent field absorption has been measured as a function of cladding refractive index and bulk absorption coefficient. A simple theory for interpreting these results has been developed. An all‐fiber species concentration sensor has been constructed and its performance characterized.
