EL-RAKHAWI ARCHITECTURE FOR TOPOLOGICAL PHOTONIC NEUROMORPHIC COMPUTING WITH NEAR-ZERO THERMAL DISSIPATION
Abstract
TPNC-NZTD: TOPOLOGICAL PHOTONIC NEUROMORPHIC COMPUTING WITH NEAR-ZERO THERMAL DISSIPATION Author: Dr. Mohamed Kamal Arafa El-RakhawiDOI: 10.5281/zenodo.23337933 A revolutionary hybrid chip architecture solving AI's energy crisis by integrating three Nobel Prize-winning phenomena: photonic computing (light instead of electrons), topological insulators (backscattering-immune edge states), and spiking neural networks (event-driven computation). Core architecture: 2D topological insulator substrate (bismuthene on SiC) + nanoscale photonic waveguides along edges + non-linear optical synapses (phase-change materials GeSbTe or 2D TMDs) + photonic neurons with thresholding behavior. Quantum-limited performance: Energy per photon at 1550 nm = 0.128 aJ. With 10-100 photons per spike for reliable detection above noise floor: E_spike = 10-100 aJ (100-1000× improvement over electronic SNNs). Thermal dissipation: 10 aJ × 1 MHz × 10⁶ synapses = 10 μW per million synapses (1,000,000× improvement over electronic chips). Computational speed: 100 GHz - 1 THz via photonic propagation. Fabrication: CMOS BEOL-compatible via heterogeneous integration (micro-transfer printing or adhesive wafer bonding of III-V materials), preserving topological bandgap integrity during processing. Applications: Edge AI/IoT ($50B), data center acceleration ($150B), autonomous systems ($30B), scientific computing ($20B), neuromorphic research ($5B). Total addressable market: $300B+ by 2030. Comprehensive IP protection: 5 patent claims covering hybrid architecture, photonic spike computation method, heterogeneous fabrication process preserving topological states, synaptic weight update protocols, and application-specific deployments.
