Paper Abstract

A few mode-microfiber knot resonator (FM-MKR) incorporating a polyvinyl alcohol (PVA) is investigated for realization of a relative humidity sensor. The transmission characteristics of the proposed FM-MKR with variations in relative humidity are measured. The sensitivity of the FM-MKR to relative humidity is effectively improved by reducing the difference of the group effective refractive.
