OPA chips may one day replace optical lenses

Caltech researchers have created an optical phased array chip that can capture images.

The technological breakthrough has the potential to revolutionize photography.

Ali Hajimiri, Bren Professor of Electrical Engineering and Medical Engineering in the Division of Engineering and Applied Science at Caltech, claims:

We’ve created a single thin layer of integrated silicon photonics that emulates the lens and sensor of a digital camera, reducing the thickness and cost of digital cameras. It can mimic a regular lens, but can switch from a fish-eye to a telephoto lens instantaneously — with just a simple adjustment in the way the array receives light.

He continues:

“The ability to control all the optical properties of a camera electronically using a paper-thin layer of low-cost silicon photonics without any mechanical movement, lenses, or mirrors, opens a new world of imagers that could look like wallpaper, blinds, or even wearable fabric.”

My take: This is the perhaps unseen conclusion of digitization. First film. Soon lenses. Both usurped by ones and zeroes. I wonder what the future of visual storytelling will look like when almost anything flat — walls, windows, ceilings — can become image capturing tools.
