Anisotropic Intensity Profiles in Ferroelectric LiNbO_3 Single Crystal Fibers

摘要

Experimental studies of laser light intensity profiles, with light propagation directionrnperpendicular to the optical c-axis, in ferroelectric single crystal fibers such as LiNbO_3 are carried out and reported. Theoretical simulations of such multimode propagation of light are also conducted for the LiNbO_3 single crystal fibers. The simulation and experimental studies are extended to and compared with the commercially available single mode and multimode silica optical fibers. Theoretical simulations provided a good account for the light intensity profiles measured and led to a preliminary interpretation of complex specklegram observed in anisotropic single crystal fibers.
