Experimental generation of optical coherence lattices
TLDR
In this article, the authors report experimental generation and measurement of recently introduced optical coherence lattices and show theoretically that information can be encoded into and, in principle, recovered from the lattice degree of coherence.Abstract:
We report experimental generation and measurement of recently introduced optical coherence lattices. The presented optical coherence lattice realization technique hinges on a superposition of mutually uncorrelated partially coherent Schell-model beams with tailored coherence properties. We show theoretically that information can be encoded into and, in principle, recovered from the lattice degree of coherence. Our results can find applications to image transmission and optical encryption.read more

Generation of Partially Coherent Beams
TL;DR: Partially coherent beams with a prescribed phase, state of polarization, and degree of coherence display many extraordinary propagation properties and are preferred in many applications, such as particle trapping, free-space optical communications, remote sensing, optical imaging, material thermal processing, image transformation, and optical encryption as discussed by the authors.

TL;DR: This work introduces an alternative optical encryption protocol whereby the information is encoded into the spatial coherence distribution of a structured random light beam via a generalized van Cittert--Zernike theorem, and shows that the proposed approach has two key advantages over its conventional counterparts.

Controllable rotating Gaussian Schell-model beams.
Lipeng Wan,Daomu Zhao +1 more
TL;DR: This work introduces a new class of partially coherent beams whose spectral density and degree of coherence tend to rotate during propagation, and it is shown that such beams can undergo a twist of more than 90 deg, providing larger degrees of freedom for flexibly tailoring the beam twist.

Propagation of optical coherence lattices in the turbulent atmosphere
TL;DR: It is shown how one can increase the distance over which the lattice periodicity reciprocity is preserved in the turbulent atmosphere by engineering input lattice beam parameters and that the OCLs have scintillation indices lower than those of Gaussian beams.

TL;DR: A new microscope using ultrathin light sheets derived from two-dimensional optical lattices is developed, demonstrating the performance advantages of lattice light-sheet microscopy compared with previous techniques and highlighted phenomena that, when seen at increased spatiotemporal detail, may hint at previously unknown biological mechanisms.

Ultracold quantum gases in optical lattices
TL;DR: Optical lattices represent a fast-paced modern and interdisciplinary field of research as discussed by the authors, and they form powerful model systems of quantum many-body systems in periodic potentials for probing nonlinear wave dynamics and strongly correlated quantum phases, building fundamental quantum gates or observing Fermi surfaces.
