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 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 ...

Nonlinear fiber optics

Soviet Journal of Quantum Electronics, 1988
The advantages of fiber waveguides over bulk nonlinear media are demonstrated. A review is given of the main nonlinear effects which occur during propagation of laser radiation in fiber waveguides. The most interesting applications of nonlinear fiber optics are discussed.

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

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 Optics in Fibers

Science, 2003
The use of fiber optics has tranformed telecommunications. In his Perspective, Mollenauer reviews some of the recent technical developments in this field that are based on the nonlinear properties of the fibers. Solitons (that is, light pulses that do not broaden as they travel) in silica fibers form the basis for the most sophisticated ...

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.

Fiber nonlinear optics

Proceedings of LEOS '93, 2002
The most significant recent development in fiber nonlinear optics is the fiber amplifier. Higher power from optical amplification directly impacts lightwave systems, optical signal processing, and lasers. Even without optical amplifiers, the trend is to higher intensities in fibers which increases the role of nonlinearities.

Novel nonlinear waves in optical fibers

Optics Letters, 1986
It is shown that a new class of radially symmetric nonlinear waves exists in an optical fiber with a third-order, optical Kerr-effect nonlinearity. The fiber has a circular cross section, and the field solutions are obtained from a scalar-wave equation that excludes any azimuthal coordinate dependence. It is assumed that the fiber has a linear core and

Unification of nonlinear-optical fiber devices

Optics Letters, 1990
Nonlinear coupling can be described in a universal form applicable to a general class of optical fiber devices involving the interaction of two modes. By knowing the solution to one type of device, we then have the solution to all other types. For example, the descriptions of birefringent fibers used as switches and amplifiers have their direct ...
