Then you should check out our new publication in Advanced Optical Materials. Thanks to the great effort in design, fabrication, and data analysis by our former group member Subhajit Bej, we were able to show that using guided-mode resonances can increase vastly the 3rd order nonlinear optical response, which might be even useful for optical switching and pulse shaping.

Congrats to all, but in particular to Subhajit for his great work.
