Few-mode fibers with improved mode spacing
2015 European Conference on Optical Communication (ECOC), 2015A simple and intuitive optimization approach is described for the design of composite rotationally asymmetric refractive index fiber profiles with substantially improved mode spacing.

Few-mode fibers provide a number of independent channels in a single strand of optical fiber. Therefore they have potential for increasing channel capacity and data throughput, stabilizing coherent systems, simplifying and miniaturizing fiber optic circuits, and multiplying the number of functions and operations which can be performed.

Mode-divison multiplexing over few-mode fibers
2016 IEEE Photonics Society Summer Topical Meeting Series (SUM), 2016We report about mode-multiplexed transmission over few-mode fibers with 10 or more spatial modes. We also describe the latest progress in mode-multiplexers and optical amplifiers.

Applications of weakly-coupled few-mode fibers [Invited]
Chinese Optics Letters (COL), 2020Space-division multiplexing (SDM) has attracted significant attention in recent years because larger transmission capacity is enabled by more degrees of freedom (DOFs) in few-mode fibers (FMFs) compared with single-mode fibers (SMFs).

Modal pattern and power in few-mode fibers, with dominant high-order modes by mode excitation at different core offset misalignments, were simulated and experimentally examined using the spatially and spectrally resolved imaging (S2) technique.

Orthogonality breaking through few-mode optical fiber
Applied Optics, 2016Polarization sensing and imaging through optical fibers is a technological challenge motivated by promising applications for in vivo, in situ polarimetric endoscopy for biomedical diagnosis. Among the recent approaches proposed to solve this issue, the depolarization/dichroism sensing by polarization orthogonality breaking (DSOB) technique was shown to

Two-Mode Coupling Model in a Few Mode Fiber
Оптика и спектроскопия, 2013A phenomenological two-mode coupling model in few mode fibers (FMF) is developed. It uses a mode coupling coefficient and the differential modal delay as the input parameters and the split-step approach. The model is consistent with the experimental results demonstrating distributed mode coupling effects in FMF and may be used for multipath ...

High-dimensional Stokes vector direct detection over few-mode fibers.
Optics Letters, 2019Direct detection attracts much attention for its simplicity compared with coherent detection. In this Letter, we propose for the first time, to the best of our knowledge, a high-dimensional Stokes vector direct detection (HD-SVDD) receiver for mode ...
