Abstract
We present a simulation framework for evaluating the effect of location-dependent variability in photonic integrated circuits. The framework combines a fast circuit simulator with circuit layout information and wafer maps of linewidth and layer thickness variations to estimate the statistics of the circuit performance through Monte-Carlo simulations. We illustrate the use of the tool on ring resonator filters, a design sweep of Mach-Zehnder lattice filters, and the tolerance optimization of a Mach-Zehnder interferometer, and show how variability aware design should become an essential part in future photonic circuit design.
