Please find the explanation below:
I don’t quite understand the second part of your question, you can visualize all the output light power spectrum at the Optical Spectrum Analyzers, however the CW laser is with single frequency so you will get the same centered spectrum outputs.
– Indeed you are right.I want to sweep the CW laser for let say C-band, please let me know how to do that.
Your original demux design actually works if you tune it carefully based on the channel spacing; the first MZI should have a FSR equals twice of the channel spacing and the second and third MZI should have a FSR equals 4 times of the channel spacing. Then all the channels will be separated at the end.
- Thanks. I already did this part, if you check the MZI delay lengths in the file I sent you. I have designed for 5 nm of channel spacing.
Please let me know if something is not clear.
