A Unified Materials Approach To Mitigating Optical Nonlinearities In Optical Fibre. Ii. B. The Optical Fibre, Material Additivity And The Nonlinear Coefficients

This paper, part IIB in a trilogy, describes the continuum models employed to deduce the effects of differential thermal expansion in the clad optical fibre in addition to the nonlinear optical behaviours at high intensities of light. State-of-the-art in W-S-based continuum material models are reviewed with specific examples provided based on canonical material systems suggested from the findings of Part I and treated in detail in Part III. Part IIB pays particular attention to the optical fibre and its nonlinearities.
