Progress in silicon-based reconfigurable and programmable all-optical signal processing chips.

We are investigating how to design, model, and test silicon‑based chips that process optical signals without using electronics. Traditional electronic signal processing is hitting limits in bandwidth and power use, so silicon photonics offers a scalable way to support high‑speed communication networks. The project centers on the architecture of programmable photonic integrated circuits (PICs). We examine how to integrate tunable optical components such as Mach‑Zehnder interferometers, ring resonators, and phase shifters. Using numerical simulations and mathematical models, we evaluate the performance of these reconfigurable chips for tasks like optical filtering, dispersion compensation, and logic operations. The study provides clear guidance on improving power efficiency, tuning speed, and chip footprint. By

creating a comprehensive simulation framework, we support the development of flexible optical networks that can route signals dynamically and manipulate waves in real time. Ultimately, the work reviews and optimizes the structure and performance of next‑generation programmable optical hardware, linking theoretical photonic designs to practical, high‑throughput communication systems.
