Video: June 16, 2023 Photonics Hot List

June 16, 2023
Here’s your Photonics Hot List for June 16, 2023, covering laser spectroscopy tech that dives deep, the realistic possibility of sapphire photonic chips, and nonlinear metasurfaces that boost frequency changes.

In this episode of Photonics Hot List...

The SETI Institute is taking optical sensing and spectroscopy to new depths…to the very bottom of the ocean, in fact. They’re revolutionizing oceanography and could someday set their sights on space exploration.

More advanced photonics integrated chips are now a very real possibility, thanks to work by researchers in the U.K. who have been able to write hundreds of waveguides in sapphire.

A team at Paderborn University has tailored nanostructured nonlinear metasurfaces to basically triple the frequency of incoming light. They’ve discovered that different parameter combinations support extreme increases in efficiency in the nonlinear frequency conversion process.
