Interferometric Fiber-Optic Gyroscope Using Multi-Core Fiber
Journal of Lightwave Technology, 2019We 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

Interferometric Fiber-Optic Gyroscope Using Multi-Core Fiber
2018 European Conference on Optical Communication (ECOC), 2018A novel configuration of an optical gyroscope which consists of multi-core fiber (MCF) and fan-in/fan-out devices is proposed. We fabricated the sensor coil by using seven-core fibers and successfully demonstrated an MCF gyroscope for the first time to our knowledge.

Recent progress on multi-core fiber
2012 17th Opto-Electronics and Communications Conference, 2012Potential of uncoupled multi-core fiber (MCF) is investigated with viewpoints of space utilization efficiency and the figure of merit (FOM). The impact of longitudinal optical coupling characterization and/or management is discussed using a dual-core fiber.

Multi-core Fiber Design and Analysis
37th European Conference and Exposition on Optical Communications, 2011Impacts of random phase offset in coupled-mode theory and autocorrelation function in coupled-power theory on crosstalk of multi-core fibers are investigated for the first time. Simulation results are in good agreement with measurement results.

Field-Deployed Multi-Core Fiber Testbed
2019 24th OptoElectronics and Communications Conference (OECC) and 2019 International Conference on Photonics in Switching and Computing (PSC), 2019We installed a multi-core fiber (MCF) cable in underground tunnels in a city in Italy, without significant crosstalk degradation in uncoupled MCFs, and with the lowest-ever spatial mode dispersion in randomly-coupled MCFs.

High-Power, All-Fiber, Yb-Doped Multi-Core Fiber Amplifier
Conference on Lasers and Electro-Optics, 2022We have demonstrated a 173 W, all-fiber multicore amplifier using a six-core single-mode Yb-doped fiber and an all-fiber multi-core pump-signal combiner. Each of Yb-doped cores has 17-µm mode-field diameter and is capable of kW-class operation.

High capacity multi-core fiber systems
2016 21st European Conference on Networks and Optical Communications (NOC), 2016We review progress on high-capacity multi-core fiber systems based on homogeneous, single mode MCF and focus on the limits of high capacity transmission. We discuss issues of inter-core crosstalk, dynamic inter-core skew and their impact on multi-core fiber systems such as pilot-tone transmission and high-dimensional modulation formats.
