roject JANUS: A Spatial Residue Number System Photonic AI Architecture with Non-Volatile Phase-Change Routing and Monolithic 3D Multi-Physics Simulation Suite (Release 4.0)

## OverviewProject JANUS is a constraint-aware, bounded-exact optoelectronic computing architecture designed to eliminate the analog optical bottleneck by replacing analog amplitude accumulation with deterministic Spatial One-Hot Residue Number System (RNS) permutations over Z₁₇...

JANUS: A Spatial Residue Number System Photonic AI Architecture with Non-Volatile Phase-Change Routing

Conventional optical AI processors encode numbers in continuous analog amplitudes (Mach-Zehnder Interferometers / MZIs), accumulating optical power across analog meshes. For a 128x128 matrix multiplication, unreduced analog accumulation requires an unattainable 138.4 dB analog SN...
