Modal dynamics in multimode fibers [PDF]
Journal of the Optical Society of America A, 2011 The dynamics of modes and their states of polarizations in multimode fibers as a function of time, space, and wavelength are experimentally and theoretically investigated. The results reveal that the states of polarizations are displaced in Poincare sphere representation when varying the angular orientations of the polarization at the incident light ...

Single multimode fiber endoscope. [PDF]
Opt Express, 2017 Multimode fibers can guide thousands of modes capable of delivering spatial information. Unfortunately, mode dispersion and coupling have so far prevented their use in endoscopic applications. To address this long-lasting challenge, we present a robust scanning fluorescence endoscope.

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 ...
