I asked to Gemini Notebook to produce a vide on Neuromorphic Photonics with microring resonators, based on our work. Here is the result. Traditional AI is hitting the "memory wall"—the massive energy cost of moving data between memory and processors. Our new video explores how silicon microring resonators (MRRs) use light-matter physics to act as "optical neurons". Key Scientific Insights: The Physics of Spiking: The competition between fast electronic blue-shifts (FCD) and slow thermal red-shifts (TO) generates native spiking and refractory periods within sub-millimeter cavities. Directional Excitability: Advanced Taiji and DRUM resonators use asymmetric coupling to ensure unidirectional signal flow, solving the photonic "axon problem". Massive Parallelism: Wavelength Division Multiplexing (WDM) mimics the dense connectivity of biological dendrites, allowing high-throughput, low-power processing. Watch our technical deep-dive to see how this multi-scale interplay of light and heat offers a sustainable path for AI hardware. 🎬👇 #NeuromorphicPhotonics #SiliconPhotonics #AIHardware #Physics #Innovation #Sustainability
