FIGURE 1. Silicon photonics couplings often deviate from clean predictable Gaussian coupling cross-section. Profiles of this sort cannot be reliably optimized with traditional alignment algorithms. Otherwise, the optimization risks locking onto one of the local optima rather than the global optimum. This can be efficiently achieved by performing an areal scan of the target area, thereby mapping the coupling cross-section across its full extent. A piezo-based scanner can achieve this in fractions of a second.
