By analyzing the data from the Dark Energy Camera Legacy Survey (DECaLS), astronomers from the Christ University in Bangalore, India, have serendipitously discovered a new ring galaxy, which received designation DES J024008.08-551047.5 ...
Scientists at Beijing Institute of Technology have developed an ultra-fast quasi-three-dimensional technology, overcoming the shortcomings of missing information in two-dimensional images and incomplete features, allowing ...
Quantum emission is pivotal to realizing photonic quantum technologies. Solid-state single photon emitters (SPEs), such as hexagonal boron nitride (hBN) defects, operate at room temperature. They are highly desirable due ...
Precise control of light is a crucial requirement in optical imaging, sensing, and communication. Traditional lenses employed for the purpose have limitations, necessitating more precise and compact solutions. To address ...
Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ellipticity) detection ...
Optical holography is a powerful method for recording and reconstructing complete optical field information, including intensity and phase. It has found extensive applications in various fields, such as optical display, imaging, ...
Vortices of light, null regions of intensity surrounded by spiral phases, make up the skeleton of a wavefield and influence the properties of light. Since the discovery of the tight connection of optical vortices and orbital ...
Mid-wavelength infrared (MWIR) as one of the most important transparent atmosphere windows is less sensitive to interference from the background emission of the sun, providing a high-transmission zone for the finger-print ...
Researchers at Columbia Engineering have developed a new class of integrated photonic devices—"leaky-wave metasurfaces"—that can convert light initially confined in an optical waveguide to an arbitrary optical pattern ...
As fundamental properties of light, spectra and polarization carry vital information concerning the propagation of light waves. For example, spectral imaging can reflect the material composition of objects, while polarized ...
