Time-reversed wave mixing in nonlinear optics [PDF]

, 2013
Time-reversal symmetry is important to optics. In linear optics, a time-reversed process to laser emission enables total absorption of coherent light fields into an optical cavity of loss by time-reversing the original gain medium.

Integrated optics for astronomical interferometry. I. Concept and astronomical applications

, 1999
We propose a new instrumental concept for long-baseline optical single-mode interferometry using integrated optics which were developed for telecommunication.

Noncanonical quantum optics [PDF]

, 2000
Modification of the right-hand-side of canonical commutation relations (CCR) naturally occurs if one considers a harmonic oscillator with indefinite frequency. Quantization of electromagnetic field by means of such a non-CCR algebra naturally removes the

Multidimensional quantum entanglement with large-scale integrated optics [PDF]

Science, 2018
Large-scale integrated quantum optics The ability to pattern optical circuits on-chip, along with coupling in single and entangled photon sources, provides the basis for an integrated quantum optics platform. Wang et al.

Marsilio Ficino's Allegorical Reading of Optical Phenomena

Teorie vědy, 2020
As a Platonist, Marsilio Ficino (1433–1499) was deeply interested in light  and its qualities. As a matter of fact, the metaphysics of light is so fundamental for him that it appears, treated more or less systematically, almost in all of his works.

Adaptive Optics for Astronomy

, 2012
Adaptive Optics is a prime example of how progress in observational astronomy can be driven by technological developments. At many observatories it is now considered to be part of a standard instrumentation suite, enabling ground-based telescopes to ...

Space‐Confined Growth of 2D InI Showing High Sensitivity in Photodetection

Advanced Electronic Materials, 2020
Layered InI has a great potential in optoelectronic applications due to its direct wide tunable bandgap. However, there is no single report about its 2D synthesis. Here, the growth of high‐quality and ultrathin InI flake (as thin as 8 nm) is reported via

Probing the conserved roles of cut in the development and function of optically different insect compound eyes

Frontiers in Cell and Developmental Biology, 2023
Astonishing functional diversity exists among arthropod eyes, yet eye development relies on deeply conserved genes. This phenomenon is best understood for early events, whereas fewer investigations have focused on the influence of later transcriptional ...

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

FEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

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.
