Optimized Multimode Interference Fiber Based Refractometer in A Reflective Interrogation Scheme [PDF]
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,

Swept-source multimode fiber imaging. [PDF]
Sci Rep, 2023 AbstractHigh-resolution compressive imaging via a flexible multimode fiber is demonstrated using a swept-laser source and wavelength dependent speckle illumination. An in-house built swept-source allowing for independent control of bandwidth and scanning range is used to explore and demonstrate a mechanically scan-free approach for high-resolution ...

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.

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.
