Analytical laser model for optical signal integrity analysis

The design of optical interconnects within an electrical environment requires a close coupling of the respective modeling and simulation tools. For the lasers in optical interconnects exist a number of different models, which usually require detailed and, for the manufacturer, sensitive information concerning the laser structure and therefore the manufacturing process. Similar problems were an issue in electronic system design, but have been solved by employing generic high-level simulation models. Taking the same approach for optical interconnects an analytical approximate solution of the laser rate equations is presented as a first step. Due to its analytical nature, the model can either use parameters derived from the laser structural data or parameters gained from measurement. This is an advantage when dealing with devices with unknown structure.
