WebGovind P. Agrawal, in Nonlinear Fiber Optics (Sixth Edition), 2024 3.4.1 Dispersion compensation. The technique of dispersion compensation combines two fibers with different characteristics such that the average GVD of the entire fiber link is reduced to zero. Even though an optical pulse would broaden if propagated in each fiber individually, it … WebAdaptive optics is a technique for measuring and correcting optical aberrations in real time. It is particularly useful for atmospheric compensation—the correction of aberrations incurred by light propagating through the atmosphere. ...
