OSA Seminar in Ratingen, Germany: Optical Metrology
Fundamentals and Capabilities of Modern Optical Spectrum Analysis
What are the different methods of spectral analysis, and which is best suited for specific applications? Which approach is most effective for characterizing modulated optical signals in the frequency domain? How can fiber-coupled signals be analyzed with high precision?
In this seminar, we will explore these and other key aspects of optical metrology, complemented by practical measurements on fundamental optical transmission systems, fiber optics, light sources, passive components, and various other optical elements. Beyond the theoretical foundations, hands-on workshops provide practical experience: Perform spectral measurements using an optical spectrum analyzer (OSA), Characterize a visible laser source, Analyze an NRZ-modulated 10G signal, Investigate the cut-off wavelength of single-mode fibers.
