A mutant seedling revealed how plant tissues scatter incoming light, allowing plants to sense its direction and move toward it. On a shelf lined with terra cotta pots, herbs bend their stems toward ...

Photonics is the study of the generation, detection, and manipulation of light waves in the form of photons. One interesting property of light is polarization, defined by its electric and magnetic ...

Today I would like to present the turbine-powered optical isolator, a steampunk-sounding bit of hardware that only allows light to pass in one direction. That, I must admit, is a sentence I never ...

Polarized light waves spin clockwise or counterclockwise as they travel, with one direction behaving differently than the other as it interacts with molecules. This directionality, called chirality or ...

Researchers have identified key structures in photosensitive plant tissue that allow them to determine the direction of light, leading to positive phototropism. A recent research collaboration between ...

Metasurface technology is an advanced optical technology that is thinner, lighter, and more capable of precisely controlling light through nanometer-sized artificial structures than conventional ...
