Integrated Photonics: The Future of Communication
Data generation and processing have grown exponentially, with more devices online than humans. Each demands increasing bandwidth and energy, pushing semiconductor technology to its limits. Integrated photonics offers a sustainable solution.
Resolving the Bandwidth Bottleneck
Two communication types drive demand: long-distance (optical fibre, lasers) and short-range wireless (5G/6G). Prof. David Marpaung is integrating these using photonic chips to boost bandwidth and reduce energy consumption.
Key Challenges
- Developing new photonic chips: Making them ultra-low-loss and high-density using materials like silicon nitride.
- Integrating components: Lasers, modulators, amplifiers, and detectors all need to be integrated on a single chip via heterogeneous integration.
- Combining photonics and electronics: To create compact and efficient systems.
- New modulator materials: To enhance electrical-to-optical signal conversion
Best of Both Worlds
Prof. Marpaung’s research in integrated microwave photonics (MWP) merges optical and radio technologies. His team has pioneered advanced RF signal processing devices, stable on-chip lasers, and tunable filters. His 2013 paper, cited over 650 times, laid the foundation for integrated MWP.
Collaboration for Innovation
To advance photonic technology, experts in electronics, material science, quantum photonics, and AI must collaborate. These efforts will unlock the full potential of integrated photonics for next-gen communications.
