The ability to achieve quantum-limited amplification of optical signals contained in optical fibers is arguably among the most important technological advances that are underlying our modern information society. In optical ...
A team of researchers at the MPQ has pioneered the integration of erbium atoms with special optical properties into a silicon crystal. The atoms can thus be connected by light at a wavelength that is commonly used in telecommunications. ...
After a 10-year research study that started by accident and was met with skepticism, a team of Northeastern University mechanical engineers was able to synthesize highly dense, ultra-narrow silicon nanowires that could revolutionize ...
Metal halide perovskites (ABX3) have emerged as promising candidates for various optoelectronic applications due to their excellent optoelectronic properties and low-cost fabrication. At present, the light-absorbing layer ...
Superconductors—wondrous materials whose resistance drop to zero below a critical temperature—show much promise to meet the growing energy demand of the global population. With potential applications in magnetic resonance ...
Crystalline lithium niobate (LN) is considered the "silicon of photonics" because of its outstanding optical properties, including a broad transparency window and high piezoelectric, acousto-optic, second-order nonlinear, ...
U.S. Naval Research Laboratory scientists launched the second Strontium Iodide Radiation Instrument (SIRI-2) instrument in December 2021 onboard Space Test Program (STP) Sat-6. SIRI-2, a gamma-ray spectrometer, will demonstrate ...
Data centers—dedicated spaces for storing, processing and disseminating data—enable everything from cloud computing to video streaming. In the process, they consume a large amount of energy transferring data back and ...
Mica, a well-known insulator, has been found to behave as a semiconductor when thinned down to a few molecular layers
Optics researchers at The University of Texas at Dallas have shown for the first time that a new method for manufacturing ultrathin semiconductors yields material in which excitons survive up to 100 times longer than in materials ...
