Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials. Lenses ...

Conceptual depictions of wavenumber-selective nonlinear wavelength conversion in Kerr photonic crystal microresonators. Spatial modulation of the microresonator inner sidewall (pictured center) with a ...

Metalenses have been used to image microscopic features of tissue and resolve details smaller than a wavelength of light. Now, Harvard researchers have turned the metalens towards space. Researchers ...

In a lab in Zurich, scientists have built something that, at first glance, shouldn’t be possible. When a beam of infrared light strikes their ultra-thin lens—barely thicker than a red blood cell—it ...

The challenge for near-eye display optics is to project the image on a display that is placed near the eye to a comfortable viewing distance to avoid visual fatigue and discomfort. By collimating ...

Researchers from the Paul Scherrer Institute, Laboratory of X-ray Nanoscience and Technologies, developed a method for producing denser circuit patterns. Modern microchips feature conductive tracks ...

Researchers at the UCLA Samueli School of Engineering, in collaboration with the Optical Systems Division at Broadcom Inc., reported a broadband, polarization-insensitive unidirectional imager that ...

(Nanowerk News) Alongside advances in artificial intelligence and widespread availability of digital content, demand for augmented / virtual reality (AR / VR) near-eye displays has surged. There is ...
