In this work a new multiparameter sensor platform based on lossy mode resonances is presented. The structure consists of a soda-lime optical slab waveguide butt-coupled to multimode optical fibers. A ...

A kind of biconically-tapered optical fiber (BTOF) modified by silica nanospheres is proposed to implement detection of refractive index (RI), especially low RI, with strong nonlinearity and enhanced ...
