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.

Active wavefront shaping for controlling and improving multimode fiber sensor [PDF]
Journal of Innovative Optical Health Sciences, 2019 Wavefront shaping (WFS) techniques have been used as a powerful tool to control light propagation in complex media, including multimode fibers. In this paper, we propose a new application of WFS for multimode fiber-based sensors.

Multimode interference filter to solve degradation on coupler common-mode rejection [PDF]
, 1998 After quantifying degradation of a common mode rejection ratio (CMRR) 3dB-coupler due to excitation of TE01 mode, a novel compact circuit including multimode interference (MMI) coupler+bend+MMI+filter (CBF) is proposed.
