Deterministic Optical Logic System Based on the Total Wave Modified Schrödinger Equation (TWMSE) and Generalized Interference Logic

PendingUS20260079381A1Digital dataLogic circuits using opto-electronic devicesWave fieldScalable parallel processing
We propose a hybrid wave-based logic model for optical computing that integrates both Total Wave Modified Schrödinger Equation (TWMSE) formulations and non-TWMSE interference field logic. This system enables deterministic collapse behavior through physical wave interactions, rather than relying on conventional transistor logic or probabilistic quantum models. In the TWMSE regime, collapse thresholds are governed by field interference between signal and control waves, allowing dynamic selection of tasks based on intensity and phase alignment. In the generalized non-TWMSE regime, similar collapse-like logic can be achieved using thresholded interference models that are classically engineered for optical domain systems. Together, these formulations enable adaptive task selection, nonlinear logic gating, and scalable parallel processing in optical chips. Our architecture supports real-time wavefield decisions and is compatible with standard photonic components such as interferometers, microring resonators, variable attenuators, and optical threshold comparators. The result is a unified logic framework for next-generation AI hardware that harnesses both quantum-inspired and classical wave interference dynamics.
