The notion of a phased array was initially articulated by Nobel Prize recipient K. F. Braun. Phased arrays have subsequently evolved into a formidable mechanism for wave manipulation. This assertion holds particularly true ...
Polaritons are quasiparticles emerging from strong interactions between light particles (i.e., photons) and matter excitations (e.g., excitons). Over the past few years, researchers have found that these quasiparticles can ...
Despite the modern world relying heavily on digital optical communication, there has not been a significant improvement in the minimum attenuation—a measure of the loss of optical power per kilometer traveled—of optical ...
New research from the University of St Andrews paves the way for holographic technology, with the potential to transform smart devices, communication, gaming and entertainment.
From precision machining to advanced microscopy, the demand for higher-power, ultrafast lasers continues to grow. Traditionally, researchers have relied on single-mode fibers to build these lasers, but they face a fundamental ...
A team of researchers has discovered how a little-known type of symmetry in quantum materials, called nonsymmorphic symmetry, governs the way these materials interact with intense laser light.
A study conducted by researchers from the Changchun Institute of Optics, Fine Mechanics and Â鶹ÒùÔºics (CIOMP) of the Chinese Academy of Sciences has demonstrated how nitrogen vacancies (VN) resolve asymmetric carrier injection ...
For years, engineers have sought better ways to build tiny, efficient lasers that can be integrated directly onto silicon chips, a key step toward faster, more capable optical communications and computing.
When light hits solar cells, so-called electron-hole pairs are created: the electrons are excited and can move almost freely in the material—i.e. to generate electricity. The electrons will leave 'positive gaps," so-called ...
Researchers at the College of Design and Engineering (CDE) at the National University of Singapore (NUS) have developed a supramolecular co-assembly platform that produces chiral soft materials with strong and stable full-color ...
