Twist-Related Speckle Variation in Graded-Index Multimode Fiber
IEEE Photonics Journal, 2018 We theoretically investigate a twist-related speckle variation in a graded-index multimode fiber. The simulation results show that by increasing the offset splicing distance between a single-mode fiber and a multimode fiber, the speckle pattern tends to ...

Fabrication and modeling of multimode fiber lenses [PDF]
Applied Optics, 2013 We report on the fabrication, modeling, and experimental verification of the emission of fiber lenses fabricated on multimode fibers in different media. Concave fiber lenses with a radius of 150 μm were fabricated onto a multimode silica fiber (100 μm core) by grinding and polishing against a ruby sphere template.

Infrared Fiber
IEEE Photonics Journal, 2013 Fiber-based multimode combiners allow for wavelength and power scaling of laser sources while maintaining a common emission aperture and divergence. For applications in the mid-infrared spectral band, chalcogenide glass optical fibers are one of the few ...

Mode multiplexer for multimode transmission in multimode fibers
Optics Express, 2011 We have numerically demonstrated an efficient mode multiplexer which can tailor the input field patterns by using a phase controller and a mode coupler formed by four single-mode fibers (SMFs). By connecting the mode multiplexer to a multimode fiber (MMF), two orthogonal higher-order modes of the MMF can be simultaneously excited to form two ...

Optimized Multimode Interference Fiber Based Refractometer in A Reflective Interrogation Scheme
Proceedings, 2018 A fiber based refractometer in a reflective interrogation scheme is investigated and optimized. A thin gold film was deposited on the tip of a coreless fiber section, which is spliced with a single mode fiber. The coreless fiber is a multimode waveguide,

Learning and Avoiding Disorder in Multimode Fibers [PDF]
Physical Review X, 2021 Multimode optical fibers (MMFs) have gained renewed interest in the past decade, emerging as a way to boost optical communication data-rates in the context of an expected saturation of current single-mode fiber-based networks. They are also attractive for endoscopic applications, offering the possibility to achieve a similar information content as ...
