a Mask of the total reference circuit. The waveguide structure is shown in blue, the Ti heaters in red. The grid size is 50 μm × 50μm; the overall size of the shown region is approximately 1900 μm × 320 μm. The black dashed rectangle indicates the area where our thermal analysis will be performed. b Detail of a single MZI from the circuit’s mask. The input and output 2 × 2 MMIs are highlighted by the black dashed rectangles on the left and right of the image. The Ti strip used for thermal tuning with the electrical pads (the red structure) covers the center portion of the upper waveguide. The grid size is 10 μm × 10 μm; the overall size of the depicted region is approximately 500 μm × 65 μm.
