From: Programmable wavelength filter with double ring loaded MZI
Experimental transmission spectra of the double ring-loaded MZI filter. Each plot shows the target design (with the \(a_i\) and \(b_i\) coefficients listed below the plot). The experimental results are obtained by optimizing the spectral response from the chip outputs by driving the on-chip actuators in real time. From the measurement we can see, the experimental results matches the simulation very well, and the overall extinction ratio exceeds 20Â dB for all designs.
