Figure | Metasurface polarimeter and experimental results. A schematic of the metasurface grating beam path (above), where the input beam is incident on a beam splitter. The light is reflected onto a ...

In this video I talk about diffraction gratings and how they work. I show you how you can use them to make diffraction patterns on chocolate or other shiny materials. Trump faces backlash over Coast ...

Scientists have unveiled a new approach to ultra-secure communication that could make quantum encryption simpler and more efficient than ever before. By harnessing a 19th-century optics phenomenon ...

An artistic view of the subwavelength grating made of layered molybdenum diselenide. The red spheres represent molybdenum atoms, and the blue ones represent selenium atoms. Light is trapped within the ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new way to structure light in custom, repeatable, three-dimensional patterns, ...

Create a new conda environment and install xluminafrom PyPI. We recommend using python=3.11: conda create -n xlumina_env python=3.11 conda activate xlumina_env pip install xlumina It should be ...

Spectrographs are important tools for studying many biological and chemical processes and substances, from pigments to plant growth and nucleic acids to pharmaceuticals, providing information about ...

Sound idea: laser light passes between a ultrasound transducer-reflector array that creates a Bragg grating of air. The laser beam interacts with this grating and is deflected without travelling ...

Most of these wastes, however, contain some of the most useful compounds in industrial settings that can be both profitable and sustainable. “Repurposing crab waste as a raw material for bioplastic ...

This paper presents a partially coherent point-diffraction digital holographic microscopy (PC-pDHM) prototype and demonstrates its application in label-free imaging of the dynamic processes of live ...

We all know that light and sound are wave phenomena, but of very different kinds. Light is electromechanical in nature, while sound is mechanical. Light can travel through a vacuum, while sound needs ...
