Intensity Dependent Refractive Index Effects in Optical Fibers and Thin Films

摘要

This final report presents research into the effects of intensity-dependentrefractive indices in optical fibers and thin films. Discussed are photosensitive gratings; second-harmonic generation in fibers and at surfaces, the theoretical investigation of all-optical switching; all-optical switching in fibers; and two-photon absorption and color center dynamics.
