Optical Computing [PDF]

open access: yesApplied Mathematics and Computation, 2009
In this survey we consider optical computers that encode data using images and compute by transforming such images. We give an overview of a number of such optical computing architectures, including descriptions of the type of hardware commonly used in optical computing, as well as some of the computational efficiencies of optical devices.

The language of Einstein spoken by optical instruments [PDF]

open access: yes, 2004
Einstein had to learn the mathematics of Lorentz transformations in order to complete his covariant formulation of Maxwell's equations. The mathematics of Lorentz transformations, called the Lorentz group, continues playing its important role in optical ...

Characterization of thermal effects in the Enhanced LIGO Input Optics [PDF]

open access: yes, 2011
We present the design and performance of the LIGO Input Optics subsystem as implemented for the sixth science run of the LIGO interferometers. The Initial LIGO Input Optics experienced thermal side effects when operating with 7 W input power. We designed,

Optical Coatings as Mirrors for Optical Diagnostics [PDF]

open access: yesJournal of Coating Science and Technology, 2016
The aim of this work was to provide a comprehensive insight concerning coated films which might be used for first mirrors in ITER. The influence of the mirror crystallite size has been addressed as well as the coating techniques to provide nanocrystalline films. Tests of coated mirrors both in laboratories and in tokamaks are reviewed.

Non-Euclidean cloaking for light waves [PDF]

open access: yes, 2009
Non-Euclidean geometry combined with transformation optics has recently led to the proposal of an invisibility cloak that avoids optical singularities and therefore can work, in principle, in a broad band of the spectrum [U. Leonhardt and T. Tyc, Science

Quantum Teleportation of Optical Quantum Gates [PDF]

open access: yes, 2002
We show that a universal set of gates for quantum computation with optics can be quantum teleported through the use of EPR entangled states, homodyne detection, and linear optics and squeezing operations conditioned on measurement outcomes.

Transformation Optics and the Geometry of Light [PDF]

open access: yes, 2008
Metamaterials are beginning to transform optics and microwave technology thanks to their versatile properties that, in many cases, can be tailored according to practical needs and desires.

Quantum optics with bosons and fermions [PDF]

open access: yes, 2008
Atom optics, a field which takes much inspiration from traditional optics, has advanced to the point that some of the fundamental experiments of quantum optics, involving photon correlations, have found atomic analogs.

Atom optics with microfabricated optical elements [PDF]

open access: yesConference Digest. 2000 International Quantum Electronics Conference (Cat. No.00TH8504), 2000
We introduce a new direction in the field of atom optics, atom interferometry, and neutral-atom quantum information processing. It is based on the use of microfabricated optical elements. With these elements versatile and integrated atom optical devices can be created in a compact fashion.

Optical-component-only adaptive optics

open access: yesOptics Letters, 2021
This Letter introduces a technique for performing binary adaptive optics, which is carried out by optical components only, without the help of any electronic or optoelectronic device. In this technique, the interferogram produced by a point diffraction interferometer modulates a light-driven crystal. The modulated light-driven crystal may produce pupil-
