Description

VCSEL lasers currently serve as the workhorse light source in optical interconnects in datacenters and other short-distance, high-bandwidth applications. The response time of these lasers to electrical modulation currently represents a major bottleneck in optical interconnect bandwidth. Therefore, improving the speed of VCSEL-based interconnects, through improved VCSEL design and fabrication as well as driver circuitry, can greatly enhance datacenter and high-performance computing capabilities. The U.C. Berkeley VCSEL Compact Model seeks to address that problem by providing a circuit simulator compatible Verilog-A model of VCSEL lasers, enabling circuit designers to develop analog and digital techniques to compensate for VCSEL performance. To that end, this model implements the semiconductor laser rate equations with quantum well capture dynamics and self-heating.
