Mid-wavelength infrared (MWIR) as one of the most important transparent atmosphere windows is less sensitive to the interference from the background emission of the sun, providing a high-transmission ...

A research team has demonstrated that silicon nanospheres can strongly enhance second-harmonic generation (SHG) from an ...

Polarization has been a central concept to our understanding of optics and has found many applications ranging from quantum science to our daily life. 3D polarization structures possess peculiar ...

Researchers discovered that crystal dislocations in antiferroelectric PbZrO3 thin films generate ordered polar antihedgehog lattices, creating a new defect-engineering approach for polar topologies.

An experimental technique that started life in nuclear and particle physics is now being used to measure chemical reactions inside the human body and to help diagnose cancer and heart disease in ...
