Large-scale photonic accelerators are fundamentally constrained by analog precision collapse, optical loss accumulation, thermal drift, and nonlinear wavelength interference. JANUS resolves these contradictions by reformulating optical computation as a spatial localization problem using One-Hot Optical Residue Number System encoding, eliminating analog amplitude reconstruction entirely. Combined with non-volatile PCM Beneš routing, distributed GaP phase-sensitive amplification, single-wavelength coherent fanout, and CRT-based exact reconstruction, the architecture operates within bounded thermal, optical, and electrical regimes. Across Mini, Edge, and Datacenter configurations, JANUS achieves sustained exact 64-bit throughput from 57.6 to 919.2 TMAC/s. Patent pending — Application No. 202611052791.
