A group led by Federico Capasso at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has broadened the study of optical singularities to include to zero-dimensional (point) and 2D (sheet) optical singularities. The group developed a way to engineer 2D singularity sheets on demand.
The advance could have practical value for numerous applications. To date, the study of optical singularities — regions of darkness surrounded by light — has centered on optical vortices. These beams have helical wavefronts and a 1D singularity along the optical axis.
“Conventional holography techniques are good at shaping light, but struggle to shape the darkness,” Capasso said. “We have…READ MORE
