Ultra-miniaturized Endoscopes with Multi-Core Fibers
Optical Fiber Communication Conference (OFC) 2020, 2020We take stock of the progress made into developing fiber-optic ultra-thin endoscopes assisted by wave front shaping. We focus on multi-core fiber-based lensless endoscopes intended for multi-photon imaging. We put the work into perspective and outline remaining challenges.

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.

Multi-core fiber undersea transmission systems
2017 European Conference on Networks and Communications (EuCNC), 2017Various potential architectures of branching units for multi-core fiber undersea transmission systems are presented. It is also investigated how different architectures of branching unit influence the number of fibers and those of inline components.

Supermodes in strongly-coupled multi-core fibers
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013Single-mode and higher-order supermodes in the strongly-coupled multi-core fibers have been investigated. These fibers offer high mode density, ease of (de)multiplexed, and tunability in mode coupling as well as differential modal group delay.

Sensitive Multi-Core Fiber by Reduced-Noise In-Fiber Interferometric Sensor
2023 International Conference on Photonics in Switching and Computing (PSC), 2023Uncoupled-core multicore fiber becomes sensitive to vibrations by a Michelson interferometer embedded inside the fiber. By employing two cores in a 5.2-km 4-core fiber, environmental noise is strongly reduced with respect to the same configuration implemented with a fiber pair in a telecom cable.

CapEx advantages of multi-core fiber networks
Photonic Network Communications, 2015We investigate capital expenditure (CapEx) advantages of multi-core fiber (MCF) networks by modeling and solving CapEx-minimized planning problem. Integer linear programming model is established, and numerical results are calculated and analyzed. We conduct the solving process under two kinds of traffic patterns of light traffic and heavy traffic.

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.

A multi-core or multi-fiber WDM System
2012 International Conference on Optical Engineering (ICOE), 2012Abstract A multi-core or multi-fiber architecture with interleaver at the fiber input and wavelength division multiplexing (WDM) demultiplexer at the fiber output is proposed. In this architecture, different channels of a WDM system are interleaved into different cores of a multi-core fiber, and therefore, the inter-channel nonlinear impairments are ...
