Effect of bending on zero dispersion operation of single-mode optical fibers
Abstract:
Perturbation theory for bent optical fibers predicts that the unperturbed (straight) propagation constant (or effective index) will be corrected by a small term that is proportional to (R(b))(-2), where R(b) is the radius of the bend. We examine how this small correction affects the chromatic dispersion of the fundamental mode, and in particular we examine the changes that occur when the fiber operates at the zero dispersion wavelength lambda(o). For a bend radius of 1 cm, lambda(o) may shift by up to 20 nm.
