High capacity optical transmission technologies in multi-core fiber
2017 16th International Conference on Optical Communications and Networks (ICOCN), 2017In this paper, we propose high capacity transmission technologies based on multi-core fiber (MCF) with both coherent and direct detections. In the coherent detection system, we experimentally demonstrate 560 Tb/s coherent optical dual-polarization DFT-S OFDM 32QAM signal transmission over 10-km single-mode 7-core fiber.

Grating Inscription to Few-Mode Multi-Core Optical Fiber
Asia Pacific Optical Sensors Conference, 2016Preliminary fiber Bragg grating inscription to 2LP-mode 4-core fiber is demonstrated to confirm feasibility for optical fiber sensing application. Clear Bragg reflection spectra for LP01 and LP11 are obtained individually using all fiber-optic few-mode multi-core input/output module.

Beam-Steering All-Optical Switch for Multi-Core Fibers
Optical Fiber Communication Conference, 2017We report on the development of the first multi-lane all-optical switch with directly integrated multi-core fibers. A 3-port single-sided beam-steering switch connecting 4-core fibers shows core-to-core losses below 2.2 dB with less than 1-dB variation.

Lensed Multi-core Fiber for Interferometric Optical Tweezing Applications
Conference on Lasers and Electro-Optics 2012, 2012We have fabricated lensed multi-core fiber using a fusion splicer. The fiber end-shaping was studied and interference between diagonal cores of the four-core singlemode probe was examined for interferometric optical tweezing applications.

The simulation research of multi-core optical fiber near-field optical tweezers
SPIE Proceedings, 2011In order to develop the near- field optical tweezers with perfect function , We design the near-field optical fiber optical tweezers basing on the multi-core of the optical fiber. Combining the total internal reflection and multi-core optical fiber, we form evanescent wave on the fiber water interface forming , and realize the capture of object .It ...

Bend and twist sensing in a multi-core optical fiber
LEOS 2008 - 21st Annual Meeting of the IEEE Lasers and Electro-Optics Society, 2008We present a method for sensing both bending and twisting in an optical fiber which is compatible with extensive multiplexing. The technique employs a multi-core fiber design, high-performance static strain sensing, and robust reconstruction algorithms.

Guided acoustic waves Brillouin scattering in multi-core optical fibers
2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017Optical fibers consisted of multiple cores (multi-core fibers, MCFs) are widely regarded as the leading solution path to the optical communications capacity crunch. MCFs are also used in high power lasers, microwave photonics, and shape-sensing applications.
