Paper Abstract

We report on a concept of the all-fiber intensity bend sensor, which is based on photonic crystal fibers with asymmetric air-hole structure. The cross-section of these fibers consists of two regions with different air-filling factors on opposite sides of the fiber core. The design enables the measurement of the bending radius as well as the bending orientation. Moreover, the mode field area of our fibers is adjusted to that of standard single mode fibers (SMFs), which allows easy fabrication of the sensor with the use of widely available light sources and detectors pigtailed with SMFs.
