Multimode optical fiber sensors
1995Of the properties of light which can be conveniently modulated, phase and polarization information are immediately lost upon entering a multimode optical fiber. This leaves intensity as the only transmittable property available for use as a modulation sensitive parameter.

Multimodal imaging through a multimode fiber
Opto-Acoustic Methods and Applications in Biophotonics IV, 2019We present a ultra-thin system that combines optical resolution photoacoustic microscopy and fluorescence imaging based on a multimode fiber and a fiber optical hydrophone with only 250µm cross section.

Multiple fiber connectors for multimode fibers
Optics Communications, 1976Abstract We report on a multiple fiber connector for multimode fibers with a low insertion loss of ⩽ 0.22 dB. The simple, standard photolithographic fabrication process involved can yield reproducibly the tight tolerances that are required for low loss connectors.

Phase-Conjugate Multimode Fiber Gyro
Topical Meeting on Photorefractive Materials, Effects, and Devices, 1987Modal scrambling is a source of noise and signal fading in fiber-optic gyros1 and therefore the best fiber-optic gyros use single-mode polarization preserving fiber and couplers2. Phase-conjugation can be used to correct for modal scrambling3-5 and to make fiber-optic gyros6-9.

Multimode interference devices with single-mode–multimode–multimode fiber structure
Applied Optics, 2014We present a single-mode-multimode-multimode (SMm) fiber structure with a few interesting device applications. Unlike the single-mode-multimode-single-mode (SMS) structure, SMm has the unique feature of more than one mode in the output fiber. A detailed physical understanding of the transmission properties, and the differences from the SMS structure ...

Multimode Fibers for Compensating Intermodal Dispersion of Graded-Index Multimode Fibers
Journal of Lightwave Technology, 2004This paper proposes a novel type of multimode dispersion compensation fiber (MM-DCF) by which the intermodal dispersion of multimode fibers (MMFs) can be effectively compensated. A theoretical model that precisely calculates the group velocities of a target MMF and its MM-DCF and the power coupling between the two fibers is applied to confirm the ...

Results of experimental studies of multimode fiber Bragg gratings on multimode fibers
Infokommunikacionnye tehnologii, 2016Nowadays fiber Bragg gratings (FBGs) are widely used in various devices and applications of fiber optics. They become a basic component for fiber optic sensor networks. The most of those both commercial and prototype fiber optic sensor systems are based on well-researched either singlemode or multimode regime of signal transmission over optical fibers.

Microscopy with multimode fibers
SPIE Proceedings, 2013Microscopes are usually thought of comprising imaging elements such as objectives and eye-piece lenses. A different type of microscope, used for endoscopy, consists of waveguiding elements such as fiber bundles, where each fiber in the bundle transports the light corresponding to one pixel in the image.

We have recently shown [1] that the basic reciprocity requirements [2,3] for sensitive fiber gyros can be met in single mode systems in which the usual polarized light source is replaced by an unpolarized source, and that certain other operational features also result which are of interest.
