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.
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.
