Conjoined 'racetracks' make new optical device possible

When we last checked in with Caltech's Kerry Vahala three years ago, his lab had recently reported the development of a new optical device called a turnkey frequency microcomb that has applications in digital communications, ...

Exploring advances in waveguide-based augmented reality displays

In recent decades, augmented reality (AR) has evolved from a futuristic concept to a tangible and pervasive technology. AR enhances our perception and interaction with the environment by seamlessly blending projected virtual ...

Researchers create first supermirrors in mid-infrared range

An international team of researchers from Austria, the United States and Switzerland have created the first supermirrors in the mid-infrared range. These mirrors are a key technology for many applications, such as optical ...

NASA engineers push limits of physics to focus light

A pair of precision-orbiting small satellites will attempt to capture the first views ever of small-scale features near the surface of the sun that scientists believe drive the heating and acceleration of solar wind.

Replacing bone saws with smart lasers

Using lasers rather than scalpels and saws has many benefits in surgery. Yet they are only used in isolated cases. But that could be about to change: laser systems are getting smarter and better all the time, as a research ...
