A beam transformed: Optical transforms like tight focussing and total internal reflection, which gives rise to an evanescent field, can lead to out-of-plane polarization components and transverse spin ...

Scientists have demonstrated dynamically and statically unpolarized single-photon generation using diamond. The Tohoku University research group of Professor Keiichi Edamatsu and Postdoctoral fellow ...

Researchers have developed new technology to convert unpolarized light into polarized light, which makes projectors that use liquid crystal technology almost twice as energy efficient. The new ...

Changing the polarization of tightly focused light could be important for future high-resolution imaging and data-storage applications. Researchers have now shown that a simple lens can do the task ...

Secure communication is an important and challenging topic for global digital data exchange and ensures the interaction of Internet of Things devices as well as private messaging between two parties.
