Optical Design and Active Optics Methods in Astronomy [PDF]

, 2013
Optical designs for astronomy involve implementation of active optics and adaptive optics from X-ray to the infrared. Developments and results of active optics methods for telescopes, spectrographs and coronagraph planet finders are presented. The high accuracy and remarkable smoothness of surfaces generated by active optics methods also allow ...

Optical Computing [PDF]

Applied 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]

, 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 ...

Non-Hermitian Multimode Interference [PDF]

Opt. Lett. 45, 1962-1965 (2020), 2020
Multi-mode interference (MMI) and self-imaging are important phenomena of diffractive wave optics with major applications in optical signal processing, beam shaping and optical sensing. Such phenomena generally arise from interference of normal modes in lossless dielectric guiding structures, however the impact of spatially-inhomogeneous optical gain ...

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

, 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,

MICADO: the E-ELT adaptive optics imaging camera [PDF]

Astronomical Telescopes + Instrumentation, 2010
MICADO is the adaptive optics imaging camera for the E-ELT. It has been designed and optimised to be mounted to the LGS-MCAO system MAORY, and will provide diffraction limited imaging over a wide (~1 arcmin) field of view.

Quantum Teleportation of Optical Quantum Gates [PDF]

, 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.

Optical Coatings as Mirrors for Optical Diagnostics [PDF]

Journal 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.

All-optical switch with two periodically curved nonlinear waveguides [PDF]

Optics Letters, 35(3) 321-323(2010), 2008
We propose a type of all-optical switch which consists of two periodically curved nonlinear optical waveguides placed in parallel. Compared to the all-optical switch based on the traditional nonlinear directional coupler with straight waveguides, this all-optical switch has much lower switching threshold power and sharper switching width.
