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 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
