Study shows ultra-thin two-dimensional materials can rotate the polarization of visible light

It has been known for centuries that light exhibits wave-like behavior in certain situations. Some materials are able to rotate the polarization, i.e. the direction of oscillation, of the light wave when the light passes through the material. This property is utilized in a central component of optical communication networks known as an "optical isolator" or "optical diode." This component allows light to propagate in one direction but blocks all light in the other direction.

A compact metasurface array-based system for single-shot spectroscopic ellipsometry measurement

Spectroscopic ellipsometry is widely adopted in semiconductor processing, such as in the manufacturing of integrated circuits, flat display panels, and solar cells. However, a conventional spectroscopic ellipsometer, as shown in Fig.1a, typically modulates the polarization state via mechanical rotation of the compensator or analyzer. For spectral detection, it either requires wavelength scanning or the use of a multi-channel spectrometer. The resulting system is often bulky, complex, and require multiple measurements.
