Hollow Fiber Coupler Sensor

We present a bi-conical optical directional coupler composed of solid and hollow core fibers. Through an evanescent wave coupling mechanism, the detection of liquid refractive index and its temperature are demonstrated. The experimental results illustrated that the sensor offers a sensitivity of [Fo...

description We present a bi-conical optical directional coupler composed of solid and hollow core fibers. Through an evanescent wave coupling mechanism, the detection of liquid refractive index and its temperature are demonstrated. The experimental results illustrated that the sensor offers a sensitivity of [Formula: see text] volts per refractive index units (V/RIU) for refractive indices ranging from [Formula: see text] to [Formula: see text] with a resolution of [Formula: see text] refractive index units (RIU).
