Crystallization behavior of ion beam sputtered HfO2 thin films and its effect on the laser-induced damage threshold
Journal of the European Optical Society-Rapid Publications - Tập 17 - Trang 1-8 - 2021
Zoltán Balogh-Michels, Igor Stevanovic, Aurelio Borzi, Andreas Bächli, Daniel Schachtler, Thomas Gischkat, Antonia Neels, Alexander Stuck, Roelene Botha
In this work, we present our results about the thermal crystallization of ion beam sputtered hafnia on 0001 SiO2 substrates and its effect on the laser-induced damage threshold (LIDT). The crystallization process was studied using in-situ X-ray diffractometry. We determined an activation energy for crystallization of 2.6 ± 0.5 eV. It was found that the growth of the crystallites follows a two-dime...... hiện toàn bộ

Three-dimensional measurement of object surface by using ellipse binary defocusing projection
Journal of the European Optical Society-Rapid Publications - Tập 13 - Trang 1-13 - 2017
Feng Lu, Chengdong Wu
The accuracy of three-dimensional measurement of object surface is always affected by the nonlinear gamma of the projector. The defocusing binary projection can overcome the nonlinear gamma distortion of the projector and reduce the effect of high harmonics without gamma calibration. Although researches have already reduced the errors to get a clear sinusoidal curve, there still leave room for imp...... hiện toàn bộ
Robust and precise algorithm for aspheric surfaces characterization by the conic section
Journal of the European Optical Society-Rapid Publications - Tập 13 - Trang 1-7 - 2017
Petr Křen
A new algorithm for precise characterisation of rotationally symmetric aspheric surfaces by the conic section and polynomial according to the ISO 10110 standard is described. The algorithm uses only the iterative linear least squares. It uses fitting the surface form in a combination with terms containing its spatial derivatives that represent infinitesimal transformations of form. The algorithm r...... hiện toàn bộ

Sequential and non-sequential simulation of volume holographic gratings
Journal of the European Optical Society-Rapid Publications - Tập 14 - Trang 1-8 - 2018
Moritz Kick, Reinhold Fieß, Wilhelm Stork
In the development process of holographic displays like holographic Head-Mounted Displays (hHMD) the simulation of the complete optical system is strongly required. This especially includes the correct behaviour of the volume holographic grating (VHG) in terms of its optical function and its diffraction efficiency. The latter is not supported by the current version of Zemax®; OpticStudio 17, one o...... hiện toàn bộ
Một phương pháp mới để lắp đặt perovskite halide chì cesium Dịch bởi AI
Journal of the European Optical Society-Rapid Publications - Tập 17 - Trang 1-7 - 2021

Perovskite halide kim loại vô cơ là những loại bán dẫn quan trọng cho các thiết bị quang điện. Việc lắp đặt thành công các màng mỏng CsPbBr3 và CsPbCl3 gần đây đã được thực hiện bằng cách phun chùm từ tính tần số radio (Radio-Frequency magnetron sputtering). Trong công trình này, chúng tôi so sánh các đặc trưng hình thái học, cấu trúc và quang học của hai vật liệu thu được bằng kỹ thuật lắp đặt nà...... hiện toàn bộ

Adaptive particle image velocimetry based on sharpness metrics
Journal of the European Optical Society-Rapid Publications - Tập 14 - Trang 1-8 - 2018
M. Teich, J. Grottke, H. Radner, L. Büttner, J. W. Czarske
Optical distortions can significantly deteriorate the measurement accuracy in particle image velocimetry systems. Such distortions can occur at fluctuating phase boundaries during flow measurement and result from the accompanied refractive index changes. The usage of a wavefront sensor can be hindered by disturbing light reflexes or scattering. A combination of sharpness metric image evaluation an...... hiện toàn bộ
Quantum dash multi-wavelength lasers for Tbit/s coherent communications and 5G wireless networks
Journal of the European Optical Society-Rapid Publications - Tập 17 - Trang 1-7 - 2021
Zhenguo Lu, Jiaren Liu, Youxin Mao, Khan Zeb, Guocheng Liu, Philip J. Poole, John Weber, Mohamed Rahim, Grzegorz Pakulski, Chunying Song, Martin Vachon, Pedro Barrios, Daniel Poitras, Shurui Wang, Weihong Jiang
We report on the design, growth, fabrication, and performance of InAs/InP quantum dash (QD) multi-wavelength lasers (MWLs) developed by the National Research Council (NRC) Canada. The key technical specifications investigated include optical and RF beating spectra, relative intensity noise (RIN), and optical phase noise of each individual wavelength channel. Data bandwidth transmission capacity of...... hiện toàn bộ
