➀ Chip-to-chip communication needs are increasing with the rapid development of information technology, and traditional electronic interconnect technologies are facing limitations in meeting high bandwidth, low latency, and low power consumption requirements.

➁ Avicena proposes that short-distance chip-to-chip communication is more like walking, focusing on simplicity and efficiency, rather than using long-distance laser communication technology which is considered as overkill.

➂ μLED technology offers advantages such as high brightness, efficiency, low power consumption, high density parallel communication, low power consumption, high reliability, and low cost.

➃ The research team designed an optical transmitter using μLED arrays and optimized the drive current and modulation rate of μLEDs for high-speed data transmission.

➄ The optical receiver design includes the use of blue light photodetectors, optimized transimpedance amplifiers, and digital offset cancellation techniques.

➅ The team achieved a 2Gbps transmission rate with a total power consumption of 0.5pJ/bit in a 130nm CMOS SOI process, and a 1.2Tbps total rate with energy efficiency less than 1pJ/bit in a 16nm process.

➆ The application of μLED technology in chip-to-chip communication shows great potential for high-performance computing and artificial intelligence.
