Traditionally, spacecraft communications to and from Earth use radio signals, which travel at the speed of light. That means there's a round-trip delay of about three seconds from Earth to the moon ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new ...

KAIST researchers tested optical frequency comb lasers as reference signals for radio astronomy, aiming to synchronize radio telescopes with light-based timing in VLBI observations.

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world ...

We may receive a commission on purchases made from links. You've spent thousands of dollars on your home theater system, with much of the upfront cost going toward your brand-new 4K TV and Dolby Atmos ...

Google’s system leverages optical circuit switching (OCS) to create direct, low-latency optical paths between TPU chips, minimizing signal conversion losses. They avoid repeated ...

Microsoft has revealed it has collaborated with Ciena to define a blueprint for what it calls a zero-trust tiered optical network architecture. In a white paper explaining the nature of the ...

First-of-Its-Kind Cryptographically Secure, Radio-Silent IFF System Is Purpose-Built for Drone Warfare Allen Control Systems (ACS), a leader in autonomous precision robotics, today announced the ...

Measuring how well blood flows to the brain is crucial for understanding a wide range of neurological issues, from strokes to migraines to traumatic brain injuries. Obtaining such measurements ...

USC engineers have developed an optical system that routes light autonomously using thermodynamic principles. Rather than relying on switches, light organizes itself much like particles in a gas ...

ROCHESTER, N.Y. — Monroe Community College has received a $3 million investment to create the nation’s first associate degree program for optical systems technology. The program will be housed at the ...
