Planar star coupler for multimode fibers
Applied Optics, 1980T-shaped network configurations cannot be used for optical data bus systems intended for passive communication between more than about ten terminals because of balanced power distribution and the severe requirements that would have to be met with respect to the dynamic range of the detectors.

Cross mode modulation in multimode fibers
Optics Letters, 2013We show that Kerr nonlinearity induced intermodal power transfer in a particular mode group of a multimode fiber can be formulated by the same type of equation used to describe the effect of cross polarization modulation in single-mode fibers.

Parametric instability in a periodic multimode fiber
2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017Modulation instability (MI) refers to a process where a weak periodic perturbation of an intense continuous wave (CW) grows exponentially as a result of the interplay between dispersion and nonlinearity. In its most basic manifestation, it can be observed in homogeneous optical fibers in the anomalous dispersion regime.

Electrooptic polarization switch for multimode fibers
Applied Optics, 1977An extensive theoretical analysis of an electrooptic polarization switch has been carried out. The main objective of the study is to ascertain whether it is possible to design such a switch with acceptable levels of optical crosstalk and control voltage if the device is used in conjunction with a multirmode optical fiber transmission system.

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.

Speckle statistics in a chaotic multimode fiber
Physical Review E, 2002Wave chaos is devoted to the study of wave motion when the geometrical limit of rays is chaotic. Imprints of ray chaos may be found either in spectral and spatial properties of modes or in spatio-temporal evolution of wave packets. In this paper, we present a thorough experimental and theoretical analysis of field statistics for light propagating in a ...

Thermooptic coupler for multimode optical fibers
Applied Optics, 1985The detailed theory is presented together with design considerations and recent experimental results for an electronically controllable directional coupler for multimode optical fibers. The device, based on plastic-clad silica fiber, is of exceptionally simple construction and compact size and is highly reliable.

Image Transmission Through Multimode Fibers
Optical Fiber Communication Conference, 2018Multimode fibers with a diameter of 100 μm can support more than 100,000 modes. It is possible to use these degrees of freedom to transmit images with the comparable number of degrees of freedom.
