<p>➀ Traditional chip cooling methods dissipate heat from the surface, creating localized hot spots (dark silicon) that limit performance and energy efficiency.</p><p>➁ Researchers propose photonic cooling using anti-Stokes fluorescence, where targeted laser light absorbs heat from inside the chip and converts it into higher-energy light, enabled by a thin photonic cold plate and optical layers.</p><p>➂ Early tests show this method outperforms conventional air/liquid cooling with lower power consumption, potentially boosting processing speeds, reducing energy use, and recycling waste heat as light energy.</p>
