Job Description

Introduction Integrated optics is currently experiencing unprecedented growth, driven largely by the rapid expansion of artificial intelligence (AI), cloud computing, and high-performance data processing applications. As AI models continue to increase in size and computational complexity, the demand for high-bandwidth, low-latency, and energy-efficient interconnects has become one of the key technological challenges in modern computing systems. Optical interconnects are emerging as a promising solution, offering significantly higher data throughput and lower power consumption compared to conventional electrical links. To fully realize the potential of integrated optical systems, continuous improvements are required at multiple levels, including system architecture, photonic integrated circuits (PICs), electronic integrated circuits (EICs), and advanced packaging technologies. The co-design and optimization of these building blocks are essential for achieving breakthroughs in data rate, power efficiency, scalability, and overall system cost. This PhD project focuses on the electronic integrated circuit components of optical communication systems, with particular emphasis on the transmitter (TX) driver and receiver (RX) transimpedance amplifier (TIA). These circuits play a critical role in determining the overall performance of optical links, directly impacting achievable bandwidth, signal integrity, energy efficiency, and system robustness. The primary objective of the project is to develop novel circuit topologies and design techniques that push the state of the art in high-speed optical interfaces. Key research goals include increasing bandwidth and data rate capability, improving the driving strength and efficiency of optical modulators, enhancing TIA sensitivity and speed, and minimizing power consumption while maintaining high performance. Through innovative circuit design and technology optimization, the project aims to contribute to the next generation of energy-efficient and cost-effective integrated optical communication systems for AI and data-centric applications.
