With Passive Approach, New Chips Reliably Unlock Color Conversion

Researchers at JQI have designed and tested new chips that reliably convert one color of light into a trio of hues. Remarkably, the chips all work without any active inputs or painstaking optimization—a major improvement over previous methods.

Researchers Identify Groovy Way to Beat Diffraction Limit

There's a limit to how tightly a lens can focus a laser beam. For researchers studying the interactions between light and matter, this makes experiments more challenging. A new chip made from a thin, grooved sheet of silver defies this limit, delivering the energy of 800-nanometer laser light to a sample in peaks and valleys just a few dozen nanometers apart.
