Multi-core optical fiber in a passive optical local area network
2018 International Conference on Innovative Trends in Computer Engineering (ITCE), 2018This paper describes cases where the new technology of multi-core fibers and passive optical networks is used to solve the problem of a lack of space in duct pipes for a computer local area network (LAN). A solution to the congestion problems in computer LANs that involves increasing the number of users per single trunk with a passive optical network ...

Uncoupled Multi-core Fiber Design for Practical Bidirectional Optical Communications
Optical Fiber Communication Conference (OFC) 2022, 2022We review and discuss the design factors and considerations on MCFs for bidirectional transmissions, including connection polarity and crosstalk requirements. We also introduce MCFs suitable for bidirectional long-haul and short-reach transmissions.

Multi-core Few-mode optical fibers with large Aeff
European Conference and Exhibition on Optical Communication, 2012We designed and fabricated 7-core and 19-core few-mode fibers with large Aeff of 170μm2 (LP01 mode). We discuss the potentials and required challenges of realizing large-Aeff multi-core few-mode fibers taking intra-core and inter-core cross-talk into account.

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 ...
