Focus issue introduction: nonlinear optics [PDF]

open access: yesOptics Express, 2011
It is now fifty years since the original observation of second harmonic generation ushered in the field of nonlinear optics, close on the heels of the invention of the laser. This feature issue celebrates this anniversary with papers that span the range from new nonlinear optical materials, through the increasingly novel methods that have been ...

An X-ray polarimeter for hard X-ray optics [PDF]

open access: yes, 2006
Development of multi-layer optics makes feasible the use of X-ray telescope at energy up to 60-80 keV: in this paper we discuss the extension of photoelectric polarimeter based on Micro Pattern Gas Chamber to high energy X-rays.

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

open access: yes, 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

Optimal Concentration of Light in Turbid Materials [PDF]

open access: yes, 2010
In turbid materials it is impossible to concentrate light into a focus with conventional optics. Recently it has been shown that the intensity on a dyed probe inside a turbid material can be enhanced by spatially shaping the wave front of light before it

Metal diffusion properties of ultra-thin high-k Sc2O3 films

open access: yesAIP Advances, 2017
The diffusion barrier properties of Sc2O3 against metal diffusion were studied. Tin and ruthenium were used as probe materials to study the barrier properties of Sc2O3 in thickness ranges that are of relevance for gate materials.

Structure of high-reflectance La/B-based multilayer mirrors with partial La nitridation

open access: yesAIP Advances, 2016
We investigate a hybrid thin film deposition procedure that significantly enhances reflectivity of La/B based nanoscale multilayer structures to be used as Extreme UV mirrors at 6.7 nm wavelength and beyond. We have analyzed the La-nitridation process in

Recent Progress in Chiral Topological Quantum Interface

open access: yesFrontiers in Physics, 2022
Chiral quantum optics and Topological photonics are both emerging field of research, which have attracted great attention in recent years. Chiral quantum optics provides a new approach to achieve full quantum control of light-matter interaction in a ...

Swept source optical coherence tomography Gabor fusion splicing technique for microscopy of thick samples using a deformable mirror [PDF]

open access: yes, 2015
We present a swept source optical coherence tomography (OCT) system at 1060 nm equipped with a wavefront sensor at 830 nm and a deformable mirror in a closed-loop adaptive optics (AO) system.

Driving superfluidity with photoassociation [PDF]

open access: yes, 2000
We theoretically examine photoassociation of a two-component Fermi degenerate gas. Our focus is on adjusting the atom-atom interaction, and thereby increasing the critical temperature of the BCS transition to the superfluid state.

Classifying Toric and Semitoric Fans by Lifting Equations from ${\rm SL}_2({\mathbb Z})$ [PDF]

open access: yes, 2018
We present an algebraic method to study four-dimensional toric varieties by lifting matrix equations from the special linear group ${\rm SL}_2({\mathbb Z})$ to its preimage in the universal cover of ${\rm SL}_2({\mathbb R})$.
