I’ve check your projects. The issue is related that the pin detected is a square law device and caused some components to disappear in the ESA. The long length fiber introduces some phase information for the missing components which allows them to appear on the ESA. Please note that when I’ve decreased the length of the fiber to 100m, the 60GHz signal disappeared as shown in the attached file.
There is a component in OptiSystem called “Optical Phase Detector” which shows all components generated by the MZM.
