SkyFabric v1.4: Architecture of a Distributed Analog Optical Correlator for Geometric Signal Recovery

This work presents the architectural consolidation of SkyFabric v1.4 — a distributed passive phase-array system that performs analog optical correlation prior to digitization. The core principle of the system is “Correlate First”: spatial geometry and optical interference perform matched filtering before any digital processing. Individual nodes operate strictly in linear regime and do not apply detection thresholds. Signal emergence occurs only at the centralized optical summation stage via coherent amplitude addition. An in silico validation using real pulsar data (PSR J1839+15) confirms √N signal-to-noise improvement through geometric phase alignment alone. The simulation demonstrates recovery of a signal buried below single-node noise floor without local detection. The architecture does not introduce new physics. It relies exclusively on:– spatial coherence,– high-Q resonant accumulation,– magneto-optical transduction,– analog optical summation. SkyFabric is defined as a Spatial Analog Optical Correlator.
