Nonlinearity in bent optical fibers

Applied Optics, 2009
An interferometric method to study the induced variations of nonlinear parameters in bent optical fiber such as third-order susceptibility chi((3)) and second-order refractive index n(2) is presented. Due to the expected nonlinear response of the Young's modulus of fiber material, the profiles of asymmetric variations of the two parameters with ...

Waveguides and fibers for nonlinear optics

Journal of the Optical Society of America B, 1988
Optical waveguides are ideal for nonlinear interactions because they provide strong beam confinement over long propagation distances. They are characterized by regions of high refractive index bounded by regions of lower refractive index. Examples of such waveguides are shown in Figure 1.

Nonlinearity of Optical Fibers: A tutorial

Optical Fiber Communication Conference, 2018
Fiber nonlinearities are regarded as being harmful for optical communication systems, although they are useful for applications such as Raman amplification and supercontinuum generation. In this tutorial I review them and discuss their practical implications.

Nonlinear optical fiber resonator: Optical fiber bistability

Wuhan University Journal of Natural Sciences, 1996
The linear and nonlinear charecteristics of verious optical fiber loop resonators have been processed uniformly using transmission matrix method. It is pointed that in nonlinear operation condition each of those optical fiber loop resonators may be used to make an all-optical fiber bistability device. The configuration, charecterictics and threshold of

Nonlinear pulse propagation in optical fibers

Optics Letters, 1978
We discuss the propagation of nonlinear optical pulses in fibers. The wave equation is solved taking the radial dependence in an average way. The radius versus wavelength curves for "no dispersion" in SiO(2) glass are calculated and plotted. These no-dispersion curves separate the regions of light and dark solitons supported by the fibers.
