Design Considerations for Phase Modulation in Testable Photonic Systems and Co-packaged Optics
🤖 AI Summary
As the complexity of silicon photonic integrated circuits increases, efficient phase modulation becomes critical for testing and calibration. This work systematically compares thermo-optic and carrier-based electro-optic phase modulation within Mach–Zehnder interferometers and microring resonators, evaluating key performance metrics—including extinction ratio, tuning efficiency, power consumption, and bandwidth—to quantitatively assess their suitability for test signal generation and calibration tasks. The study elucidates fundamental trade-offs among modulation speed, energy efficiency, and controllability, offering clear criteria and design guidance for selecting phase modulation strategies that enhance testability in highly integrated silicon photonic systems.
📝 Abstract
As silicon photonic integrated circuits (PICs) scale in complexity, testing and calibration increasingly depend on effective phase modulation mechanisms. This work compares thermally induced phase modulation and carrier-based electrical modulation in Mach-Zehnder and microring modulators. The devices are designed and evaluated for extinction ratio, tuning efficiency, power consumption, and modulation bandwidth. The study identifies key trade-offs among modulation speed, energy consumption, and tuning controllability that directly influence the suitability of these methods for test signal generation and calibration tasks. The results highlight the relative advantages and limitations of thermal and electrical approaches across different operating regimes. These findings provide practical design guidance for selecting phase modulation strategies in scalable silicon photonic systems with integrated test and calibration requirements.
