Full-set mode analysis of three-mode fibers calculated from polarization components of near-field pattern
TL;DR: In this paper, the amplitude components and phase differences from the intensity profiles that passed through a polarizer with angles of 0, 45, and 90° were calculated for a graded-index three-mode fiber and the off-axis mode excitation ratio was compared with theoretical ones.

Abstract: We propose and demonstrate a novel mode analysis method that can provide a full set of amplitudes, phases, and polarization states of guided modes including degenerate modes in few-mode fibers. The method is based on the calculation of amplitude components and phase differences from the intensity profiles that passed through a polarizer with angles of 0, 45, and 90°. The accuracies of calculation formulas are shown by simulation to be less than 10−10 for amplitudes and 10−3 rad for phase differences. The method was applied to a graded-index three-mode fiber, and the off-axis mode excitation ratio characteristics were compared with theoretical ones.

Mode Splitting Based on Polarization Manipulation in Few-Mode Fiber
TL;DR: In this article, a three-paddle two-mode fiber polarization controller (TMPC) was used for mode splitting in a fewmode fiber (FMF) to achieve high mode extinction ratio (>30 dB), good power stability (≤0.5 dB), and stable mode profile position.

Comprehensive quantitative analysis of vector beam states based on vector field reconstruction
TL;DR: It is argued that the cylindrically polarized LG modal decomposition is meaningful for the detail discussion of experimental results, such as analyses of mode purities and mode contaminations, and the VFR technique is significant for analyses of polarization structured beams generated by lasers and converters.

Spatially and spectrally resolved imaging of modal content in large-mode-area fibers
TL;DR: A new measurement technique, capable of quantifying the number and type of modes propagating in large-mode-area fibers is both proposed and demonstrated, based on both spatially and spectrally resolving the image of the output of the fiber under test.
