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 ...

Deep learning of ultrafast pulses with a multimode fiber
APL Photonics, 2020 Characterizing ultrashort optical pulses has always been a critical but difficult task, which has a broad range of applications. We propose and demonstrate a self-referenced method of characterizing ultrafast pulses with a multimode fiber. The linear and

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.
