Interferometric Fiber-Optic Gyroscope Using Multi-Core Fiber [PDF]
Journal of Lightwave Technology, 2019 We proposed a novel interferometric fiber optic gyro (I-FOG) sensor coil consisting of multi-core fiber (MCF) spliced with fan-in/fan-out (FIFO) devices. We fabricated a 102-m long, seven-core MCF coil with FIFO devices and demonstrated the operation of the proposed I-FOG for the first time to our knowledge. The angular random walk performance of 0.002
