Abstract

A novel fiber-optic sensor structure fabricated by cascading two optical microfiber knot resonators (MKRs) is proposed and demonstrated in this paper. A theoretical analysis for describing the principle of such a microfiber double-knot resonators (MDKRs) based sensing structure is given while an experiment is carried out to verify the design. Experimental results show that high-precision and simultaneous multi-point temperature sensing in micro-scale can be achieved by using this structure. Such a MDKRs based sensor also shows the potential for achieving dual-parameter measurement to eliminate the cross-talk in small scale.
