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 ...
Researchers at MPQ in Garching, together with a team from TU Munich, have excited erbium atoms embedded in crystalline silicon such that they emit single photons. Their special properties can form the basis for the development ...
The bonds between clusters of elements in the fourteenth group of the periodic table are known to be fickle. Ranging from the nonmetal carbon, to the metalloids silicon and germanium, to the metals tin and lead, all these ...
Researchers in Singapore have developed the world's smallest LED (light-emitting diode) that enables the conversion of existing mobile phone cameras into high-resolution microscopes. Smaller than the wavelength of light, ...
Stars emit light that travels through empty space without significant attenuation. The visual signal is essentially lossless until detected. After many years and billions of kilometers, starlight-photons may eventually encounter ...
Integrated photonics is making strides towards hosting an increasing range of functionalities on a chip. Examples include information processing and computation as well as optical sensing and ranging applications. This has ...
Purdue University researchers found that by tailoring the film thickness of conducting nitrides and oxides, specifically plasmonic titanium nitride (TiN) and aluminum-doped zinc oxide (AZO), they can control the materials' ...
A new miniscule nitrogen dioxide sensor could help protect the environment from vehicle pollutants that cause lung disease and acid rain.
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. ...
