Building robust optical structures made of darkness

Optical devices and materials allow scientists and engineers to harness light for research and real-world applications, like sensing and microscopy. Federico Capasso's group at the Harvard John A. Paulson School of Engineering ...

Using optics to trace the flow of microplastics in oceans

Microplastics are tiny plastic particles less than 5 mm in diameter that have emerged as a novel marine environment pollutant. Microplastics usually result from a breakdown of larger plastic debris but can also be generated ...

Optical indicators based on cholesteric liquid crystal polymers

Optical indicators based colored polymers are autonomous responsive labels that provide an optical signal to represent a specific exposure over time. Polymers that possess a high degree of order can establish structural color, ...

The handedness of light holds the key to better optical control

Researchers at Aalto University's School of Electrical Engineering have developed a new approach to control the properties of a light beam. By using the handedness of the light beam, the technique achieves significantly enhanced ...
