"surrounding tiny silicon structures with liquid crystals dynamically controls light pathways without fixed electrodes... then, using optical torque rotate liquid crystal molecules/ shift surface's resonance in real time by shining laser onto it... 3rd-harmonic generation converts IR into green-yellow light, simultaneously modulating conversion output... functions alterable post-fabrication... dynamic all-optical energy-efficient: neural networks, high-speed telecommunications/ routers, computers"
