Researchers led by Federico Capasso at the Harvard John A. Paulson School of Engineering and Applied Science (SEAS) have developed a 2-mm achromatic metalens capable of focusing RGB colors without aberrations. The researchers also developed a miniaturized display for virtual reality and augmented reality applications.
Capasso’s lab was successful in previously developing achromatic aberration-free metalenses in 2018. At just tens of microns in diameter, though, the lenses were too small for practical use in VR and AR applications.
“This state-of-the-art lens opens a path to a new type of virtual reality platform and overcomes the bottleneck that has slowed the progress of new optical device,” Capasso said. He…READ MORE
