“…EMGA is based on classical Gaussian approximation [25] of radial mode field distribution ( ) ( ) in the weakly guiding optical waveguide with an arbitrary refractive index profile by the well-known Laguerre-Gauss function expression [4,25,100], describing a mode field distribution in weakly guiding optical waveguide with ideal infinite parabolic index profile:…”

“…By means of numerical solution (11), the normalized equivalent mode field radius 0 will be obtained. Then 0 is substituted to the expression (10), and mode core parameter is estimated; that permits evaluating the propagation constant for guided mode by the wellknown expression [4,[25][26][27]55, 100]:…”

“…It is widely applied for estimation of insertion loss and reflection at the splices of the same type optical fibers with nonidentical technologic parameters [117][118][119][120][121], modeling, and research of the influence of launch conditions on optical waveguide mode composition excitation [25,[122][123][124] including the modeling of a fewmode optical signal propagation over multimode fibers [4,8,10]. Generally, the coupling coefficient of injected mode with excited mode is determined by the overlap integral of interacting mode fields [4,8,10,[117][118][119][120][121][122][123][124]:…”

“…Modern commercial multi-Gigabit transmission transceivers are realized on Vertical Cavity Surface Emitting Lasers (VCSELs) or single-mode Fabry-Perot laser diodes (LD) [1][2][3][4]. Because emission from the conventional VCSEL usually consists of about 5 or 6 transversal modes with maximal azimuthal order not more than 3, and single-mode LD injects just fundamental and lower-order modes 01 and technique of signal generation, conversion and processing in transceivers of multi-Gigabit communication systems.…”

This work presents an alternative model of multimode fiber links with conventional silica weakly-guiding graded-index irregular multimode fibers under a few-mode optical signal propagation generated by laser source. The proposed model is based on the piecewise regular representation. It takes into account launch conditions, differential mode delay, both lower-and higherorder mode chromatic dispersion, differential mode attenuation, and mode mixing and power diffusion occurring due to real fiber irregularity and micro-and macrobends. We present some results of introduced model approbation with following pulse propagation simulations. A close matching with measured pulse responses at the output of test fibers is noticed.

A multifunctional all‐fiber device that can simultaneously serve as a multimode‐to‐single mode converter and a wavelength filter is presented in this article. The device has a concatenated structure consisting of a multimode fiber, a hollow core fiber, a single‐mode core mode blocker (made of magnetic nanoparticles), and a long period fiber grating fabricated in a single mode fiber. A quantitative theoretical analysis and experiments are carried out. A device with an extinction ratio of 25.7 dB and an insertion loss of −6.8 dB is obtained, and its performance should be able to be further improved by optimizing the fabrication process in future. © 2011 Wiley Periodicals, Inc.
