A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with X-ray pulses being circulated between crystal mirrors and amplified in the ...

Guided-mode resonance filters (GMRFs) and cavity resonators represent a transformative class of optical devices that exploit the resonant coupling between incident light and leaky modes in dielectric ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2024.230033 discusses non-volatile dynamically switchable color display via chalcogenide stepwise cavity resonators. In the field of color ...

Optical cavities, also known as optical resonators, are structures that confine light within a small volume by utilizing highly reflective surfaces. These cavities allow light to circulate or bounce ...

Non-classical states of light such as single photons and entangled photons are key ingredients for chips dedicated to quantum computation, quantum sensing, quantum measurement, etc. Fabrication of a ...

Using a standard CMOS process, researchers have combined acoustic MEMS and other technology to create a >10-GHz on-chip resonator function for filters and VCOs. How standard CMOS process can be used ...

(Nanowerk Spotlight) Metamaterials (MMs) are those materials whose properties are mainly based on their design and structure, rather than the actual materials used to realize them [1]. Sensors based ...

Increasing the intensity of the interaction between light and matter to create, for example, better photodetectors or quantum light sources is a key objective in quantum optics and photonics.
