Journal ArticleDOI
Spreading of partially coherent beams in random media
Greg Gbur,Emil Wolf +1 more
TL;DR: This suggestion that partially coherent beams may be less susceptible to distortions caused by propagation through random media than fully coherent beams is studied quantitatively by examining the mean squared width of partially incoherent beams in such media as a function of the propagation distance.
Journal ArticleDOI
Vortex beam propagation through atmospheric turbulence and topological charge conservation
Greg Gbur,Robert K. Tyson +1 more
TL;DR: The propagation of vortex beams through weak-to-strong atmospheric turbulence is simulated and it is demonstrated that the topological charge of such a beam is a robust quantity that could be used as an information carrier in optical communications.
Journal ArticleDOI
Plasmon-assisted two-slit transmission: Young's experiment revisited.
Hugo F. Schouten,Nikolay V. Kuzmin,Guilhem Dubois,Taco D. Visser,Greg Gbur,Paul F. A. Alkemade,H. P. Blok,G.W. 't Hooft,G.W. 't Hooft,Daan Lenstra,Daan Lenstra,Eric R. Eliel +11 more
TL;DR: The total intensity of the far-field double-slit pattern is shown to be reduced or enhanced as a function of the wavelength of the incident light beam, attributed to an interference phenomenon at each of the slits, instead of at the detector.
Journal ArticleDOI
Anomalous behavior of spectra near phase singularities of focused waves.
TL;DR: It is shown that remarkable spectral changes take place in the neighborhood of phase singularities near the focus of a converging, spatially fully coherent polychromatic wave diffracted at an aperture.
Journal ArticleDOI
Scintillation of nonuniformly polarized beams in atmospheric turbulence.
TL;DR: It is demonstrated, through numerical simulations, that an appropriately chosen nonuniformly polarized coherent optical field can have appreciably smaller scintillation than comparable beams of uniform polarization.
