Homogeneous and heterogeneous multi-core fibers
2012 IEEE Photonics Society Summer Topical Meeting Series, 2012Reduction of inter-core crosstalk in uncoupled multi-core fibers (MCFs) is the most critical issue for long-haul space division multiplexing transmission. In homogeneous MCFs, the crosstalk is degraded as increasing a bending radius. On the other hand, in heterogeneous MCFs, the crosstalk can be drastically reduced when a bending radius is larger than ...

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.

Simple Multi-core Optical Fiber Accelerometer
Advanced Photonics 2018 (BGPP, IPR, NP, NOMA, Sensors, Networks, SPPCom, SOF), 2018We report on a compact accelerometer built with strongly coupled multi-core optical fiber. The device was placed in cantilever position. An ultra-miniature seismic mass was used to tune the device sensitivity and operating frequency range.

Multi-core to 7 single-core-fibers fan-out device with multi-core fiber pigtail connector
SPIE Proceedings, 2014Multi-core to 7 single-core-fibers fan-out device with multi-core fiber pigtail connector is demonstrated to apply various types of multi-core fiber based sensor. Fused taper type fan-out device and SC type multi-core fiber connector are separately fabricated on each process. The fan-out device and the pigtail multi-core fiber are spliced each other by

Programmable Gain Equalizer for Multi-Core Fiber Amplifiers
Optical Fiber Communication Conference: Postdeadline Papers, 2014We demonstrate a programmable gain equalizer for 7-core fiber that can independently equalize spectra or block wavelengths in each core across the C-band. It is spliced directly to a side-pumped multi-core amplifying fiber.

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 ...

Fabrication of fiber-embedded multi-core photonic crystal fibers
Chinese Optics Letters, 2008A novel fabrication method of multi-core photonic crystal fibers is proposed on the basis of a fiber-embedded technique. A taper tower is used to modify the structures of the fiber preform, and four steps of fiber fabrication and different structures of fiber samples are given. The mode structures and beating characteristics of a photonic crystal fiber

All-Fiber Phase-locked Multi-core Photonic Crystal Fiber Laser
Advances in Optical Materials, 2011We propose and demonstrated all-fiber in-phase mode selection in an Yb-doped multi-core photonic crystal fiber laser. A high slope efficiency of 71% and significantly improved beam profile by fill-factor enlargement were achieved.
