摘要

A characterization concept for high-speed lightwave components based on high-frequency RF modulation of the test signals is introduced. The concept is first explained by using the example of optical transmission measurements covering optical loss, modulation bandwidth, and length measurements. Subsequently, optical reflection measurements with the capability of separating multiple reflections with millimeter resolution and kilometer range without a dead zone are investigated. In addition, responsivity measurements of electrooptical devices, such as lasers and photodiodes, are investigated.
