Hello Guilin,

 

Thank you for he reply. I understand we have a MZ device, but from the individual S matrix, we do not expect a resonance, as the phase shift is set to zero. 

Furthermore, notice how there is two lines plotted in the figure, a blue, close to 100% transmission line (the expected transmission) plus a green, close to zero transmission line, which shows the weird spikes. When summing blue and green at the wavelengths where the spikes appear, a transmission >100% is measured.

 

Please let me know what to think of this.

Best,

Maarten
