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 ...

Multimodal endo-microscopy using multimode fibers
Imaging and Applied Optics Congress, 2020We present and discuss the recent advances to use multimode fibers for multimodal endo-microscopy and its implementation for in-vivo imaging.

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.

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.

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 ...

Imaging using multimode fibers
Optics in the Life Sciences, 2013We demonstrate high resolution fluorescent imaging using multimode fibers in conjunction with Digital Phase Conjugation to undo the randomness of the light propagation within the multimode fibers. High-resolution images of stained biological samples are presented.

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.

Bidirectional multimode fiber interconnection
SPIE Proceedings, 2012We summarize the properties of 850nm wavelength AlGaAs/GaAs-based transceiver chips, monolithically integrating vertical-cavity surface-emitting lasers (VCSELs) and metal-semiconductor-metal (MSM) or PIN-type (p-doped-intrinsic-n-doped) photodiodes. Different chip designs enable half- and full-duplex bidirectional optical interconnection at multiple

Holography and phase conjugation were proposed in the middle 1960's for cor- recting the distortions in imaging systems due to aberrating or scattering media. These early methods have been revisited in recent years and successful experimental demonstrations have been reported with digital holographic methods in which the recording and reconstruction of

Nonlinear Waves in Multimode Fibers
2017We overview recent advances in the field of nonlinear guided wave propagation in multimode fibers. It is only in recent years that the study of nonlinear optics in multimode fibers has experienced a revival of research interest. Nonlinear arrays of linearly coupled multicore fibers permit spatiotemporal reshaping and coherent combining of ultrashort ...
