Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the “Poisson spot” to create stable patterns of light called “optical skyrmions”.
Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the “Poisson spot” to create stable patterns of light called “optical skyrmions”.
Optical skyrmions are tiny, swirling configurations in the properties of light – akin to the spikes of a hedgehog.
The team used a laser directed at a small circular disc, instead of the complex and costly engineered materials commonly used to generate these skyrmions.
This new method gives scientists a much simpler way to generate, study and adjust optical skyrmions.
