Estimation of Local Phase Errors in Silicon Photonic MZI Mesh from Passive Measurements
An algorithm is developed to extract component-level phase errors of photonic integrated circuits from its passive transmission characteristics. This algorithm successfully reduces the optical crosstalk from -10dB to -40dB in <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$4\times 4$</tex> MZI feedfor-ward mesh architecture.
