Standard extrusion creates perfectly vertical walls. If your process involves sloped sidewalls (common in deep reactive-ion etching), check if your KLayout 2.5D plugin or macro supports sidewall angle configurations to simulate a more realistic physical cross-section. Conclusion
Photonics components like waveguides, grating couplers, and ring resonators depend on precise layer thicknesses to guide light. Visualizing the stack ensures cladding and core layers are properly positioned.
