Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...

A never-before-seen image of individual oxygen atoms dissolved in water has been captured.

The deep-rooted beliefs that light absorption and scattering are totally harmful to fluorescence catching urge most researchers to chase a perfect window with minimal photon absorption and scattering ...

In a development that could reshape the future of microelectronics, optics, and biomedicine, researchers from Jinan University, in collaboration with the Institute of Chemistry at the Chinese Academy ...

Modern life runs on light. Fiber-optic cables move data across continents, lasers guide surgeries, and photons sit at the ...
