Controlled manipulation of light by cooperative response of atoms in an optical lattice [PDF]

, 2012
We show that a cooperative atom response in an optical lattice to resonant incident light can be employed for precise control and manipulation of light on a subwavelength scale.

Loss-tolerant operations in parity-code linear optics quantum computing [PDF]

, 2007
A heavy focus for optical quantum computing is the introduction of error-correction, and the minimisation of resource requirements. We detail a complete encoding and manipulation scheme designed for linear optics quantum computing, incorporating scalable

Manipulation of Single Neutral Atoms in Optical Lattices

, 2006
We analyze a scheme to manipulate quantum states of neutral atoms at individual sites of optical lattices using focused laser beams. Spatial distributions of focused laser intensities induce position-dependent energy shifts of hyperfine states, which ...

Quantum dot enabled thermal imaging of optofluidic devices [PDF]

, 2012
Quantum dot thermal imaging has been used to analyse the chromatic dependence of laser-induced thermal effects inside optofluidic devices with monolithically integrated near-infrared waveguides. We demonstrate how microchannel optical local heating plays

Low-cost optical manipulation using hanging droplets of PDMS [PDF]

, 2015
We propose and demonstrate a low-cost optical micromanipulation system that makes use of simple microfrabricated components coupled to a smartphone camera for imaging. Layering hanging droplets of polydimethylsiloxane (PDMS) on microscope coverslips, and
