Cascaded dual-tapered optical microfiber sensors for simultaneous detection of refractive indices in multiple solutions

A cascaded single-mode tapered fiber (SMTF) has been investigated for simultaneous detection of two refractive indices (RI). Two SMTFs with distinct-free spectral range (FSR) of 3.88 nm and 23.23 nm were concatenated to realize the cascaded SMTF. The interaction between evanescent waves generated by...
