Nonlinear propagation in multi-mode fibers

SPIE Proceedings, 2013
Due to the ever increasing capacity demands for optical communication links, single-mode fibers will soon not be able to support the exponential growth of data rates. A strong candidate to overcome the upcoming capacity crunch is spacedivision multiplexing (SDM) where different parallel paths in one fiber are used to transmit independent data streams ...

Twist effects in multi-mode fibers

2014 Third Mediterranean Photonics Conference, 2014
The recent interest in spatial division multiplexing as a tool to increase optical fiber communication link capacity has recently revived the interest in multi-mode optical fibers. Mode coupling within such fibers is a critical aspect of propagation, for it poses a limit to system capacity.

Passively mode-locked multi-mode fiber laser

Technical Digest. Summaries of papers presented at the Conference on Lasers and Electro-Optics. Postconference Edition. CLEO '99. Conference on Lasers and Electro-Optics (IEEE Cat. No.99CH37013), 2003
Summary form only given. Fiber amplifiers and lasers based on multimode (MM) fibers have recently allowed a great increase in the pulse peak powers and pulse energies available from a fiber optic geometry. These advances are made possible due to the increase in mode-size of the fundamental mode feasible with MM fibers. To date, however, applications of

Imaging with Multi-mode Fibers

Optics in the Life Sciences, 2015
We describe how fibers capable of transmitting multiple spatial modes can be used as imaging devices. Both wide field and scanning microscopy modalities are demonstrated. Digital phase conjugation is used to eliminate distortions.

MIMO Processing of Multi-mode Fiber Links

2006 IEEE LEOS Annual Meeting Conference Proceedings, 2006
Multiple-Input Multiple-Output (MIMO) processing of multi-mode fibers using dual launches, a two-segment photo-detector and an electronic MIMO-DFE is proposed. The potential benefits are demonstrated using capacity for the 108 fiber model as the performance metric.

Passive mode-locking using multi-mode fiber

SPIE Proceedings, 2011
The mode-locking of dissipative soliton fiber lasers using large mode area fiber supporting multiple transverse modes is studied experimentally and theoretically. Experiments using large core step-index fiber, photonic crystal fiber, and chirally-coupled core fiber show that when the higher order mode content exceeds -27 dB, the maximum stable ...

Characterization of Long Multi-Mode Fiber Links using Digital Holography

Optical Fiber Communications Conference and Exhibition, 2019
We propose to use digital holography to characterize long multi-mode fiber links. A four segment 26.5km fiber span supporting 45 spatial modes is analyzed, showing the evolution of both mode-dependent loss and cross talk.

850 nm Single-Mode VCSEL for Error-Free 60 Gbit/s OOK Operation and Transmission through 800 m of Multi-Mode Fiber

Optical Fiber Communications Conference and Exhibition, 2019
We report 60 Gbit/s OOK data transmission with directly modulated 850 nm single-mode VCSELs without applying equalization or digital signal processing. Data transmission over 800 m of multi-mode fiber is demonstrated.

Nonlinearities in Tapered Multi Mode Fibers

CLEO 2024
We demonstrate propagation of higher order modes in fiber tapers with negligible intermodal coupling, enabling wavelength control of dispersive wave generation in a single LP0,m mode around 800nm.
