'Microring' device could aid in future optical technologies

(PhysOrg.com) -- Researchers at Purdue University and the National Institute of Standards and Technology (NIST) have created a device small enough to fit on a computer chip that converts continuous laser light into numerous ...

Verifying whisky using laser light

Researchers from the University of St Andrews have developed an innovative new technique using lasers to accurately measure the authenticity of some of the world's most exclusive whiskies—without ever removing the cap.

Compressing photonic signals for greater bandwidth

Cornell researchers have developed an ingenious method to time-compress optical signals. The process could enable optical communication systems to carry many more bits per second or could also be used to generate short bursts ...

How do robots 'see' the world?

The world has gone mad for robots with articles talking almost every day about the coming of the robot revolution. But is all the hype, excitement and sometimes fear justified? Is the robot revolution really coming?

Switching light on and off - with photons

(PhysOrg.com) -- Cornell researchers have demonstrated that the passage of a light beam through an optical fiber can be controlled by just a few photons of another light beam.

New optical memory cell achieves record data-storage density

Researchers have demonstrated a new technique that can store more optical data in a smaller space than was previously possible on-chip. This technique improves upon the phase-change optical memory cell, which uses light to ...
