Transceiver circuits for high-baudrate optical interconnects

Abstract

New circuit architectures and technologies for high-speed electronic and photonic integrated circuits are essential to realize optical interconnects with higher symbol rate. As a consequence of the increasing speeds, close integration and co-design of photonic and electronic chips have become a necessity to realize high-performance transceivers with novel packaging approaches. Extensive co-design also enables the design of new electro-optic architectures to create and process optical signals more efficiently. This paper and presentation will illustrate a number of recent developments of application-specific high-speed electrooptic transceiver circuits including e.g. broadband driver amplifiers, transimpedance amplifiers, analog equalizers and multiplexer circuits for signal generation and reception at 100 Gbaud and beyond. The basic concepts and architectures, technological aspects, design challenges and trade-offs will be discussed.
