Moiré Metalenses Show Wide Focal Length Tunability

The odd, wavy pattern that results from viewing certain phone or computer screens through polarized glasses has led researchers to take a step toward thinner, lighter-weight lenses. Called moiré, the pattern is made by laying one material with opaque and translucent parts at an angle over another material of similar contrast.

Graphene-Based Hybrid Material Enables Efficient Light Conversion of Invisible Light

Nonlinear optical conversion – i.e. the process by which an incident light beam of a certain wavelength turns into rays of different wavelengths, due to its interaction with the material it passes through – is relevant to for many current and future technologies, such as imaging, information storage and processing, telecommunication, quantum technologies, and other fields.
