Lossy mode resonances can be obtained in the transmission spectrum of cladding removed
multimode optical fiber coated with a thin-film. The sensitivity of these devices to changes
in the properties of the coating or the surrounding medium can be optimized by means of
the adequate parameterization of the coating refractive index, the coating thickness and the
surrounding medium refractive index (SMRI). Some basic rules of design, which enable
the selection of the best parameters for each specific sensing application, are indicated in
this work.
