Slow-light incorporated Si modulators for RF photonic applications

RPI ID:
2022-020-301, 2022-020-401

Innovation Summary:
The disclosed system introduces slow-light photonic modulators that enhance RF photonic signal processing by leveraging engineered dispersion to reduce group velocity within integrated photonic circuits. This slowed propagation increases the interaction time between optical and RF signals, improving modulation efficiency and fidelity. The modulators are designed for compatibility with silicon photonics platforms, enabling compact and scalable integration. These features support high-performance analog photonic links for advanced communication and sensing applications.

Challenges / Opportunities:
RF photonic systems often suffer from limited modulation bandwidth and efficiency due to rapid signal transit and short interaction lengths. By introducing slow-light effects, this technology extends modulation interaction without increasing device size. There is significant opportunity for deployment in radar, high-speed communications, and next-generation sensing systems. Its CMOS-compatible design enhances manufacturability and commercial adoption.

Key Benefits / Advantages:
✔ Enhanced RF modulation efficiency
✔ Compact and scalable photonic integration
✔ Improved signal fidelity via slow-light effects
✔ Silicon photonics compatibility
✔ Supports high-bandwidth analog photonic links

Applications:
• RF photonic signal processing and communications
