Optical fibers coated with non-linear Langmuir-Blodgett films

Thin Solid Films, 1988
Abstract We report second harmonic generation (SHG) in structures composed of optical fiber cores coated with Langmuir-Blodgett non-linear films. Such structures may serve as attractive alternatives to currently available coated slab non-linear waveguides.

Optical switching using optical Kerr non-linear effect on photonic crystal fiber

2016 International Conference on Signal Processing and Communication (ICSC), 2016
This paper describes the results of the investigation of nonlinear propagation of short optical pulses in a photonic crystal fibers. It has been observed that nonlinear intensity-dependent effect can be used to determine the transmission and rejection of propagating pulses. The optical switching is achieved using Kerr nonlinear effect to shift the band

Polarization rotation in nonlinear bimodal optical fibers

Journal of Lightwave Technology, 1989
The current interest in lightwave polarization developement and nonlinear optics has centred on birefringent single-mode fibers [1]. We consider circular core fibers supporting second order modes. In the linear case a natural polarization rotation phenomenon occurs [2] and we describe its development as nonlinear effects become important.

Assorted non-linear optics in microchannel waveguides of photonic-crystal fibers

Optics Communications, 2005
Unamplified 50-fs Ti:sapphire laser pulses are used to demonstrate physically different scenarios of non-linear-optical spectral transformations in the normal and anomalous dispersion regions in microchannel waveguides off the central core in photonic-crystal fibers.

Fiber crystal growth from the melt for non-linear optical applications

Journal of Thermal Analysis and Calorimetry, 2012
During several years, we have been involved in the growth and characterization of non-linear optical crystals by the two most common techniques for growing single-crystal fibers from the melt: laser-heated pedestal growth and micro-pulling down. Their specific features are presented in this study and their versatility is demonstrated through two ...

Impact of fiber non-linearities in transmission across geographical optical networks

Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society, 2002
The introduction of a transparent optical level in a very large area transport network requires transmission through optical paths thousands of kilometers long. The Kerr effect in such networks causes nonlinear crosstalk due to Four-Wave Mixing (EWM) among channels, that is a quite detrimental, limiting the achievable spectral efficiency of the WDM ...

Fiber Non-linear Effects in Multiple-wavelengths Optical CDMA Systems

IETE Technical Review, 2013
AbstractMulti-wavelength Optical Code Division Multiple Access (OCDMA) systems suffer from fiber impairments including non-linear effects (NLE), especially when the number of wavelengths and input power level increase. In this paper, a review of NLE, including self-phase modulation, cross-phase modulation, four wave mixing (FWM), stimulated Brillouin ...

Second-order non-linear optical effects in BiB3O6 glass fibers

Optical Materials, 2004
Abstract Photo-induced second harmonic generation was found in BiB3O6 (BiBO) glass fibers with diameters 0.7–1.9 mm. We have revealed that maximum of the output second-order optical susceptibility is achieved for the fibers having diameters about 1.1 mm.

Analysis and Reduction of Fiber Non-linearity in Optical Communication System

2019
In this paper, the effect of nonlinearity has been investigated with different techniques such as non-return-to-zero (NRZ), return-to-zero (RZ), duo-binary return-to-zero (DRZ), and modified duo-binary return-to-zero (MDRZ) modulations. We have explored the fiber nonlinearities by taking dispersion of single-mode optical fiber at 2.5 Gbps communication
