Exciting a localized beam in an Anderson localizing fiber results in a high degree of output spatial coherence. The fringe patterns resemble those from singlemode fibers, indicating that a single localized mode is predominantly excited.John Ballato is a professor of materials science and engineering at Clemson University, Clemson, SC, USA, where he is the inaugural holder of the Sirrine Endowed Chair in Optical Fiber.

Laser cooling in silica has recently been demonst The realization that twisted light beams with helical phasefronts could carry orbital angular momentum (OAM) that is in excess of the photon's spin angular momentum (SAM) has spawned various important applications. One example is the design of novel imaging systems that achieve three-dimensional (3D) imaging in a single snapshot via the rotation of point spread function (PSF). Based on a ...We investigate the gradual emergence of the disorder-related phenomena in intermediate regimes between a deterministic periodic Bragg grating and a fully random grating and highlight two critical properties of partially disordered Bragg gratings. First, the integral of the logarithm of the transmittance over the reciprocal wavevector space is a conserved quantity. Therefore, adding disorder ...
