Electromagnetic energy in the terahertz region of the spectrum – nominally 300 GHz/0.3 THz to 10 THz, although some consider it to start at 100 GHz/0.1 THz – presents a technical dilemma. On one hand, ...

Traditional computer chips run on electricity, while the emerging photonic chips use light. Now, scientists at Harvard have demonstrated a new kind of chip that transmits data in the form of sound ...

A study on the chip titled "Electrical control of surface acoustic waves" has been published in the journal Nature Electronics. Researchers from the Harvard John A. Paulson School of Engineering and ...

The terahertz quantum cascade laser on its mounting. Credit: University of Leeds Lasers that switch on and off billions of times per second are the backbone of optical communications networks, but ...

Potential applications for time-of-flight (ToF) optical sensors continue to proliferate, with the market for 3D imaging and sensing expected to continue its rapid growth. A project at Stanford ...

Standard image sensors, like the billion or so already installed in practically every smartphone in use today, capture light intensity and color. Relying on common, off-the-shelf sensor technology – ...
