Light is notoriously fast. Its speed is crucial for rapid information exchange, but as light zips through materials, its chances of interacting and exciting atoms and molecules can become very small. If scientists can put ...
A way of shrinking the devices used in quantum sensing systems has been developed by researchers at the UK Quantum Technology Hub Sensors and Timing, which is led by the University of Birmingham.
There are many types of light—some visible and some invisible to the human eye. For example, our eyes and brain don't have the tools to process ultraviolet light when it hits our eyes, making it invisible. But there is another ...
A new technology that can allow for better light control without requiring large, difficult-to-integrate materials and structures has been developed by Penn State researchers. The new photonic integrated chip could allow ...
Topological photonics underpins a promising paradigm for robust light manipulation, as well as smart design of optical devices with improved reliability and advanced functionalities that are governed by the nontrivial band ...
Tailoring and manipulating electromagnetic wave propagation has been of great interest within the scientific community for many decades. In this context, wave propagation has been engineered by properly introducing spatial ...
A new method will make it possible to create compact devices that will accurately determine molecular composition of a liquid or gas, and help identify potentially dangerous chemical compounds. The results of the work carried ...
Nanophotonics considers how light and matter at the nanoscale interact with each other, with findings in the field being important for nanofabrication techniques and in future photonic devices. Until recently, metallic nanoparticles ...
Terahertz radiation, or T-rays, has barely been exploited compared to most of the rest of the electromagnetic spectrum. Yet T-rays potentially have applications in next-generation wireless communications (6G/7G), security ...
A plasmonic spin-Hall nanograting structure that simultaneously detects both the polarization and phase singularities of the incident beam is reported. The nanograting is symmetry-breaking with different periods for the upper ...
