Scientists created miniature "light traps" by placing tungsten disulfide monolayers over nanoscale air cavities carved into bismuth telluride crystals, boosting light emission up to 20 times and nonlinear optical signals 25 times stronger. The inverted confinement approach concentrates optical fields where the atom-thin semiconductor sits, overcoming limitations of conventional resonators for next-generation photonic technologies.
