Researchers have introduced a new way to create multicolored lenses that could pave the way for a generation of compact, low-cost, and high-performance optics for portable technologies like drones and smartphones.
According to Mr. Joshua Jordaan, lead author of the study from the Research School of Physics at the Australian National University and the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS), the design employs stacked layers of metamaterials. These layers make it possible to focus multiple wavelengths from an unpolarized light source across a wide diameter, addressing one of the main drawbacks of traditional metalenses.
“Our design has a lot of nice features that make it applicable to practical devices.”
“It’s easy to manufacture because it has a low aspect ratio and each layer can be fabricated individually and then packaged together, it’s also polarization insensitive, and is potentially scalable through mature semiconductor nanofabrication platforms,” Mr Jordaan said.
