A chip that can classify nearly two billion images per second
Closeup of microchip detail with dots representing systems.

Using a deep neural network of optical waveguides, the researchers’ chip—smaller than a square centimeter—can detect and classify an image in less than a nanosecond, all without the need for a separate processor or memory unit. (Image: Ella Maru Studio/Penn Engineering Today)

A chip that can classify nearly two billion images per second

Using a deep neural network of optical waveguides, a new chip developed by Penn engineers—smaller than a square centimeter—can detect and classify an image in less than a nanosecond, all without the need for a separate processor or memory unit.

Discovering new ways to control light
Microscopic view of iron phosphorous trisulfide.

The different colors in this sample of iron phosphorous trisulfide (FePS3) correspond to regions with varying thicknesses, which form different “cavity” modes at different wavelengths. (Image: Penn Engineering Today)

Discovering new ways to control light

Researchers found a magnetic property in a class of materials that enables light manipulation on the nanoscale, with implications for applications such as information storage and energy harvesting.

Artist rendering of the Starshot Lightsail spacecraft during acceleration by a ground-based laser array. Previous conceptions of lightsails have imagined them being passively pushed by light from the sun, but Starshot’s laser-based approach requires rethinking the sail’s shape and composition so it won’t melt or tear during acceleration.

How to design a sail that won’t tear or melt on an interstellar voyage

The Breakthrough Starshot Initiative’s laser-based approach requires rethinking a sail’s shape and composition so it won’t melt or tear during acceleration and pushed by wind, not light.

Homepage image: No one type of medical imaging can capture every relevant piece of information about a patient at once. Digital twins, or multiscale, physics-based simulations of biological systems, would allow clinicians to accurately infer more vital statistics from fewer data points.

Refining data into knowledge, turning knowledge into action

Penn Engineering researchers are using data science to answer fundamental questions that challenge the globe—from genetics to materials design.

New atomically-thin material could improve efficiency of light-based tech
Rendering of layers of anatomically-thin material.

So-called “two-dimensional” materials have unique electrical and photonic properties, but their ultrathin form factors present practical challenges when incorporated into devices. Penn Engineering researchers have now demonstrated a method for making large-area “superlattices”—layered structures containing 2D lattices of sulfur and tungsten—that can achieve light-matter coupling.

New atomically-thin material could improve efficiency of light-based tech

A new photodetector design from Penn Engineering is not only extremely thin, making it lightweight and cost effective, it can also emit light, not just detect it.

Simulation of glacial calving and tsunami waves predicts climate change consequences

Researchers at the School of Engineering and Applied Science have created a computer model that can accurately simulate tsunamis caused by glacial calving, critical to hazard assessments and mitigation measures in coastal regions regarding climate change.
