A Converter for Transmission With Singlemode Performance on OM2/3/4/5 Multimode Fibers

Magnetic Field Sensing Based on Magnetic-Fluid-Clad Multimode-Singlemode-Multimode Fiber Structures

Magnetic field sensing based on magnetic-fluid-clad multimode-singlemode- multimode fiber structures is proposed and experimentalized. The structures are fabricated out using fiber fusion splicing techniques. The sensing principle is based on the interference between the core mode and cladding modes. Two interference dips are observed in our spectral range. Experimental results indicate that th...

Low Frequency Noise Characteristics of Multimode and Singlemode Laser Diodes

Mode-multiplexed transmission over conventional graded-index multimode fibers.

We present experimental results for combined mode-multiplexed and wavelength multiplexed transmission over conventional graded-index multimode fibers. We use mode-selective photonic lanterns as mode couplers to precisely excite a subset of the modes of the multimode fiber and additionally to compensate for the differential group delay between the excited modes. Spatial mode filters are added to...

Modal decomposition technique for multimode fibers.

We propose a new solution for modal decomposition in multimode fibers, based on a spectral and spatial imaging technique. The appearance of spurious modes in the spectral and spatial processing of the images at the output of the fiber under test when it has more than two modes is demonstrated theoretically. The new method, which allows us to identify spurious modes, is more accurate, simpler, a...

Reviewing Spatial and Temporal Transmission of Information through Multimode Optical Fibers in a Unified Model

The potential and the capacity of large core fibers possibility to use it as a transmission media is discussed.The transmission of spatial and temporal data down a multimode optical fiber is abstracted. The attempts to establish a multi channel link over multimode fibers is reviewed and different practical methods are compared and a multimode fiber link is presented in a model which can be appl...
