A team of researchers from the Institute of Optics of CSIC and the Institute of Photonic Sciences (ICFO) of Barcelona has proposed a new design to implement highly directional single-photon sources, which constitutes an improvement ...
By enabling the recording and reconstruction of faint light beams containing a single particle of light, a new technique opens the door to holographic imaging of remote objects.
Light, with its countless colors, is one of the wonders of nature. To truly understand what we see, it is essential to know the precise colors of the light with which we perceive our world. We achieve this by means of optical ...
In the photonic synthetic dimension, the coupling of internal degrees of freedom of photons, such as frequency, spatial mode, and orbital angular momentum, generates extra dimensions in addition to real space. This approach ...
Refractive index—the ratio of the speed of electromagnetic radiation in a medium to its speed in a vacuum—can be modulated fast enough to generate photonic time crystals (PTCs) in the near-visible part of the spectrum, ...
For over a decade, teams have been working to design and prepare for the rebirth of the APS. Now, the moment is here.
Constant monitoring of vital health signs is needed in a variety of clinical environments such as intensive care units, for patients with critical health conditions, health monitoring in aged care facilities and prisons, ...
Researchers report a new single-photon Raman lidar system that operates underwater and can remotely distinguish various substances. They also show that the new system can detect the thickness of the oil underwater up to 12 ...
The data centers and high-performance computers that run artificial intelligence programs, such as large language models, aren't limited by the sheer computational power of their individual nodes. It's another problem—the ...
In the realm of photonics, the integration of multiple optical devices onto a single substrate holds immense promise for a wide range of applications. This revolutionary approach, known as photonic integration, offers remarkable ...
