This book consists of 10 chapters and begins with an overview of the fiber characteristics that are important for understanding nonlinear effects in optical fibers.

A brief historical perspective of the progress in the field of fiber optics is provided. Fiber properties such as optical loss, chromatic dispersion, and birefringence are Edition: 1. Instability in a double-coupler nonlinear fiber ring resonator has been investigated by using a linear stability analysis.

Numerical results show that although Ikeda instability appears in the positive-branch regions, it hardly interrupts bistable device application since the threshold power for instability is one or two orders of magnitude larger than the switching power for optical by: Abstract.

Case 1: When A = 0 (input of fiber 1), B = 0 (input of fiber 3) i.e., both the input intensities are below the threshold value, we get light output of fiber 2 only (because due to linear effect of the material of coupling length L c, as discussed in NOT logic operation).That is when A = B = 0, we get Y 1 = 0 and Y 2 = Case 2: When A = 1 (input of fiber 1), B = 0 (input of fiber 3) i.e Cited by: With a simple model, scaling laws are obtained for self-compression in the limit of a large soliton number.

Numerical results for Gaussian and hyperbolic-secant initial pulse shapes and various initial amplitudes are used to verify the approximate analytic result and to determine accurate scaling constants. Self-decompression (self-dispersion) is also treated in the same fashion.

In optical fiber, coupling co-efficient of each mode in a multimode fiber core has a finite value. Sometimes its value comes as (+*i), where i is the imaginary term.
