Journal ArticleDOI
Enhanced nonlinear optical response of composite materials.
George L. Fischer,Robert W. Boyd,Russell J. Gehr,Samson A. Jenekhe,John A. Osaheni,John E. Sipe,Laura A. Weller-Brophy +6 more
TL;DR: Experimental results are presented which demonstrate that the effective third-order susceptibility of a composite optical material can exceed those of the materials from which it is constructed.
Journal ArticleDOI
Stochastic dynamics of stimulated Brillouin scattering in an optical fiber
TL;DR: Gain narrowing of the Stokes spectrum is observed as the input laser power is increased, and large stochastic fluctuations are observed in theStokes output intensity.
Journal ArticleDOI
Observation of superluminal and slow light propagation in erbium-doped optical fiber
Aaron Schweinsberg,Nick N. Lepeshkin,Nick N. Lepeshkin,Matthew S. Bigelow,Matthew S. Bigelow,Robert W. Boyd,Sebastián Jarabo +6 more
TL;DR: In this paper, the authors observed both extremely slow and superluminal pulse propagation speeds at room temperature in an erbium-doped fiber (EDF) with varying powers of a 980 nm pump.
Journal ArticleDOI
Intuitive explanation of the phase anomaly of focused light beams
TL;DR: In this article, an intuitive argument is presented for the phase anomaly, that is, the 180° phase shift of a light wave in passing through a focus, and the treatment is based on the geometrical properties of Gaussian light beams.
Journal ArticleDOI
High-order thermal ghost imaging
TL;DR: It is shown that high-order ghost imaging has higher visibility and contrast-to-noise ratio as compared to conventional thermal ghost imaging and the optimal polynomial order is obtained that gives the best contrast- to-Noise ratio.
