Tiny tubes and far away stars—large metalens images the night sky

By Guest Contributor / March 5, 2024

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences developed a method for creating 100-millimeter-diameter metalenses. Scaling up metalenses to this size makes applications in astronomy and free-space optical communications possible.

A ‘hole’ new approach to metalens design

By Lisa McDonald / October 22, 2021

Traditionally, metalenses use nanoscale arrays of columns or fin-like structures to focus light. In a new open-access paper, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences developed a metalens that uses very deep, very narrow holes instead.

Video: Fish-inspired robots coordinate movements without any outside control

By Lisa McDonald / February 3, 2021

Autonomous robots, which can perform tasks with little to no human intervention or interaction, are desirable in a variety of applications, including spaceflight, household maintenance, and delivering goods. Researchers at Harvard University developed fish-shaped robots called Bluebots that can autonomously self-organize in water, which may be useful for environmental monitoring.
