How to add the power of these four detectors together, or how to realize the code, the accessory is a four-channel WDM. Is there any detector that can directly obtain the power value at multiple wavelengths?
You may use the "Electrical Adder" elements to add the signal output from the PDs, and you can use script to do it as well. To get the power versus wavelength result, you can add an Osccilloscope to the circuit to collect this result and use the "getresult" command to get this result for further process.
