Optical devices are more and more involved in time and frequency applications. They may be used for frequency reference signal distribution in a system, taking benefit of the low losses of the optical fibers, and of their small size and their immunity to electrical parasitic signals. They may also be used to realize high quality resonators and delay lines, leading to equivalent Q factors which are difficult to reach with classical RF or microwave techniques. It is important to be able to compute microwave-optical links and systems. Specially, phase noise system. This paper gives an overview of various approaches which can be used to describe an optical device with an equivalent electrical circuit, or simply with a mathematical model, and to include this model in the chosen CAD tool. We have worked with Agilent ADS microwave simulation software.
