The ESIS-II mission aims to capture high-speed “snapshot” images of the Sun’s transition region and corona. To achieve this, ...
Abstract: Grating couplers (GCs) are extensively employed in silicon photonics platforms as the I/O interfaces for data transmission between the chips and fiber systems. Perfectly vertical grating ...
Researchers have demonstrated a fiber Bragg grating for high-quality and flexible wavelength filtering of broadband optical signals Image Credit: “optic fiber” by fhisa at Openverse.org To improve how ...
Researchers experimentally demonstrate flexible and customizable filtering of broadband optical signals using chirped and tilted fiber Bragg grating technique NEW YORK, Sept. 16, 2025 /PRNewswire/ -- ...
An app nearly prevented me from picking up my own child this week. My younger daughter’s day camp has a convoluted, high-tech authorization system. Before camp started, I needed to log into its ...
In an era demanding ever-smaller, more efficient, and higher-performing light sources, particularly in the short-wave infrared (SWIR) spectrum crucial for telecom and advanced sensing, a quiet ...
A new Microelectromechanical system (MEMS) grating modulator has been developed, offering significant advancements in optical efficiency and scalability for communication systems. By integrating a ...
Abstract: Two-dimensional (2D) diffraction gratings offer a polarization-independent coupling solution between the planar photonic chips and optical fibers, with advantages including placement ...
Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...
