In this work discuss an application of chemical method, i.e., Tollen’s reagent, for mirror fabrication on the end-face of the fiber with induced long-period grating (LPG). This simple and versatile technique can be used for thin silver layer deposition and formation of stable and well-reflecting mirrors for fiber-based devices. We have found that the LPGbased sensors working in reflective configuration at dispersion turning point (DTP) of higher order cladding modes allow for refractive index (RI) measurements with sensitivity reaching 4.429 nm/RIU. Such structures, after their proper biofunctionalization process, can be used as probes for label-free biosensing.
