Optical interconnection system analysis using SPICE

With the increasing speed and capacity of data transfer systems, there is a growing interest for optical interconnection systems. In designing optical interconnection systems, reliable and easy-to-use CAD tools are required that can handle both electrical and optical devices. One approach for realizing such CAD tools is using SPICE, a widely used electrical circuit simulator, with equivalent circuit models for optical devices. In the paper, equivalent SPICE circuit models for a laser diode (LD) and a photodetector (PD) are implemented and system analysis is performed for a simple optical interconnection system having LD, LD driver circuitry, fiber, PD, and receiver circuitry.
