Fused Fiber Mode Couplers for Few-Mode Transmission

IEEE Photonics Technology Letters, 2012
Space-division multiplexing (SDM) based on few-mode fibers has been studied as a promising technique to increase fiber capacity. In this letter, we show optimal design and simulation of a low-loss fused fiber mode coupler, one of the most critical enabling components for SDM transmission systems.

Complex imaging for detecting few-mode fiber modes

Advanced Photonics 2017 (IPR, NOMA, Sensors, Networks, SPPCom, PS), 2017
We present coherent imaging for acquiring two-dimensional optical image that recovers amplitude and phase simultaneously. With coherent imaging, we detect few-mode-fiber modes with high extinction-ratio, and perform mode decomposition and differential mode delay measurement.

Few-mode fiber technology for mode division multiplexing

Optical Fiber Technology, 2017
Abstract We review recent progress on few-mode fiber (FMF) technologies for mode-division multiplexing (MDM) transmission. First, we introduce fibers for use without and with multiple-input multiple-output (MIMO) digital signal processing (DSP) to compensate for modal crosstalk, and briefly report recent work on FMF for use without/with a MIMO DSP ...

Few-mode optical fiber for mode-division multiplexing

Optical Fiber Technology, 2011
Abstract This paper describes the group delay difference and mode coupling of few-mode fiber for “uncoupled” mode division multiplexing. Optical mode separation is compatible with few-mode fiber. It has complementary characteristics with the MIMO technique.

Few-mode fibers for mode division multiplexing transmission

SPIE Proceedings, 2012
A study is presented of the fiber properties needed to achieve 10-mode multiplexing transmission. A combination of MIMO processing with optical LP mode separation is proposed to prevent the need for massive MIMO computation. The impact of mode crosstalk, differential mode delay, and the mode dependent loss of the few-mode fibers on mode multiplexing

Mode manipulation based on few-mode fiber devices

2019 18th International Conference on Optical Communications and Networks (ICOCN), 2019
In this paper, several kinds of few-mode fiber (FMF) based devices has been designed. Then an all-FMF mode-locked ring laser with carbon nanotubes was demonstrated with the generation of high purity cylindrical vector beams (CVBs).
