Transverse Anderson Localization In Disordered Optical Fibers, Salman Karbasivalashani

Theses and Dissertations

In any wave-guiding system, disorder and randomness in the wave propagation medium are

considered as annoyances that result in wave scattering and inefficient wave transport. In contrast, in this work, the disorder is utilized in the transverse directions of an optical fiber for an effective light transport. The transversely disordered refractive index profile is invariant along the direction of propagation that results in transverse Anderson localization of light. A launched beam of light into the disordered fiber initially expands until it reaches the localization regime then propagates without further expansion in the transverse directions.
