Concentrates on "powerful" nonlinear situations, when light guides itself in a homogenous medium without any intervening core-cladding structure: in short, light induces its own guiding structure. This title outlines the fundamentals of electromagnetic theory used to derive various important equations for optical fiber waveguides.
Light-induced fibres: light guiding light When the refractive index changes with the intensity of light, a number of interesting nonlinear phenomena can occur. In this chapter, we concentrate on "powerful" nonlinear situations, when light guides itself in a homogenous medium without any intervening core-cladding structure. In other words, light itself induces its own guiding structure. This fascinating phenomena has been studied theoretically with many confirming experiments. Light guiding light offers a multitude of devices wherein light becomes the master of its own destiny and allows for the possibility of rewritable circuitry. There are various approaches for describing highly nonlinear phenomena like self-induced waveguides. One is formal and lacks intuition. This approach is to solve Maxwell's equations from the outset with an intensity-dependent refractive index, completely ignoring the physics of the earlier chapters.The other approach is to build on our earlier chapters, by recognising that a light indued waveguide is a waveguide just like those we have already studied; the only difference being that its refractive index (and hence its V value) is now dependent on the intensity of light.

The intent here is not to provide an exhaustive coverage of each topic, but to connect the analytical methodology to the earlier content of the book and also to provide simple physical insight wherever possible. We propose to include the following topics that have evolved into key aspects of optical communications & sensing over the last 20 years and with which we have been involved in research-wise: Optical couplers Planar waveguides & devices Fibre/waveguide Bragg gratings & devices Holey & photonic bandgap optical fibres Optical amplifiers Faraday effect & sensors Non-linear phenomena together with appropriate references
