Resonant Mode Characteristics of Microfiber Knot-Type Ring Resonator and Its Salinity Sensing Experiment


The microfiber knot-type ring resonator is widely used in sensing, and the resonant mode is an essential concern. In this paper, resonant mode characteristics of microfiber knot-type ring resonator are studied theoretically. Results show that resonant mode split occurs when the deviation angle is large enough under the condition that the input is linearly… (More)
