Universal mesoscopic statistics and the localization of light (2009)
Park, Jongchul, Zhang, Sheng, Genack, Azriel Z.
We follow the evolution with sample thickness, of intensity statistics for localized light transmitted through layered media in a crossover from one to three dimensions occasioned by transverse...
Photon delocalization transition in dimensional crossover in layered media (2009)
Zhang, Sheng, Park, Jongchul, Milner, Valery, Genack, Azriel Z.
We report a crossover in optical propagation in random layered media from localization towards diffusion as the interaction of the wave with the sample is transformed from one to three-dimensional...
Zhang, Sheng, Lockerman, Yitzchak, Genack, Azriel Z.
We have measured the local and global statistics of singularity velocity, v, and have related these through the spatial correlation function of v. The distribution of v is a mixture of a mesoscopic...
Statistics of diffusive and localized fields in the vortex core (2007)
Zhang, Sheng, Genack, Azriel Z
The statistics of the field structure in the vortex core surrounding phase singularities in random wave fields are measured and calculated for diffusive and localized waves. Excellent agreement is...
Zhang, Sheng, Hu, Bing, Sebbah, Patrick, Genack, Azriel Z
All random wave fields possess a network of phase singularities. We show that while the phase statistics within speckle patterns is generic, the statistics of the motion of phase singularities...
Extended quasimodes within nominally localized random waveguides (2006)
Sebbah, Patrick, Hu, Bing, Klosner, Jerome M., Genack, Azriel Z.
We have measured the spatial and spectral dependence of the microwave field inside an open absorbing waveguide filled with randomly juxtaposed dielectric slabs in the spectral region in which the...
Twist Defect in Chiral Photonic Structures (2002)
Kopp, Victor I., Genack, Azriel Z.
We demonstrate that twisting one part of a chiral photonic structure about its helical axis produces a single circularly polarized localized mode that gives rise to an anomalous crossover in...
Large Coherence Area Thin-Film Photonic Stop-Band Lasers (2000)
Kopp, Victor I., Zhang, Zhao-Qing, Genack, Azriel Z.
We demonstrate that the shift of the stop band position with increasing oblique angle in periodic structures results in a wide transverse exponential field distribution corresponding to strong...
