China’s researchers have developed the world’s first intelligent chip capable of full-band, ultra-high-speed communication, laying a hardware foundation that aligns with evolving 6G standards. Published in Nature and reported by Science and Technology Daily, this photonic-electronic fusion chip can tune across a vast frequency range with unprecedented reconfigurability.
Why It Matters
Traditional chips are limited to specific frequency bands. This novel chip, based on thin-film lithium niobate photonic materials, bridges multiple bands—from low frequencies to high-end terahertz ranges—on a single platform. It offers reconfigurable, low-noise performance across 0.5 GHz to 115 GHz, enabling adaptability essential for emerging 6G, AI-native, and holographic network demands.
Key Features & Capabilities
- Broadband Frequency Agility: Supports real-time reconfiguration across nearly eight octaves—0.5 GHz up to 115 GHz—in just 180 μs.
- Ultra-High Data Rate: Demonstrates wireless transmission rates above 100 Gbps, meeting early 6G requirements.
- AI-Native Network Readiness: Fueled by built-in adaptivity, the chip can dynamically adjust communication parameters based on environmental sensing, crucial for future AI-native networks. Global Times
Strategic Impact
