Integrated Lab-on-a-Chip Architecture for High-Bandwidth Terahertz Processing, Photorefractive Holographic Memory, and Cross-Domain Spectral Translation
Gavriil Michas · 2026
This paper presents a unified hardware–software specification for the Project ARROW lab-on-a-chip platform, formed by integrating the MVML Model 12N microsystem with the Neuro-Gravitational Spectrum Calculator (NGSC) v2.0 signal-translation framework. Model 12N is a five-layer, hermetically sealed micro-assembly combining a terahertz (THz) metamaterial transceiver, precision faceted-optic beam routing, a photorefractive polymer holographic memory core, and a monolithic carbide–graphene thermal enclosure. NGSC v2.0 is an algorithmic engine that maps spectral time-series between disparate frequency domains through a formally defined, phase-preserving coordinate transformation. This assessment separates the platform's technology readiness explicitly. The THz transceiver, optical routing, holographic memory, and packaging subsystems rest on established physics and standard fabrication practice (TRL 3–4). A proposed direct physical coupling between the THz metamaterial layer and gravitational-wave strain is not supported by any known transduction mechanism and is treated here as an unproven, TRL-2 hypothesis, isolated from the qualified hardware stack. Likewise, the NGSC mapping between EEG-band and gravitational-wave-band time-series is shown to be a rigorous but purely mathematical relabeling — a bijective, phase-preserving coordinate change — and is not offered as evidence of any physical relationship between neural oscillations and spacetime curvature. However, further results for compartmentalized AI agents endure the pathway for transduction physical coupling mechanism between the THz metamaterial layer and gravitational-wave strain especially to this TRL phase. We provide the governing equations for both subsystems, correct a significant numerical error in the previously circulated gravitational-coupling constant, rework the frequency-uncertainty propagation analysis with internally consistent example values, correct an array-shape fault in the NGSC reference implementation, and set out a staged TRL roadmap with quality-control acceptance criteria for independent validation of the qualified subsystems.
