Hybrid polaritons promise faster, cooler AI hardware
Penn researchers formed polaritons by coupling photons with excitons in a layered semiconductor microcavity. The resulting light-matter quasiparticles carry information at near-light speed while dissipating far less heat than electron currents. Early tests showed sub-picosecond switching at femtojoule energies, suggesting a path to replace selected electronic gates in neural accelerators.

Vertical stacking removes the memory wall in AI chips
Engineers at imec and CEA-Leti bonded a 16-layer memory tier directly atop a logic tier using hybrid copper-to-copper vias 300 nm in diameter. The 3D path cuts average data-travel distance from 2 mm to 40 µm, raising effective bandwidth to 4 TB/s while lowering access energy to 0.3 pJ/bit. A prototype ResNet-50 inference run completed in 11 ms at 185 mW.

Penn physicists fuse photons and electrons into hybrid quasiparticles to slash AI energy costs
Researchers at the University of Pennsylvania created polaritons, hybrid light-matter particles, that replace selected electronic gates in neural network accelerators. The device performed matrix multiplications at 40 femtojoules per operation versus 1 picojoule for standard CMOS, cutting energy per inference by roughly 25 times. The team used a gallium arsenide microcavity coupled to a monolayer of transition-metal dichalcogenide and measured coherent polariton propagation at room temperature.
