Fabrication Tolerance-Aware Schematic-Driven PIC Design (Talk at AngelTech Live III 2021)
Webinars
PIC fabrication tolerances are inevitable and strongly degrade device yield, unless their impact on overall performance characteristics is considered during the design process. We present a general-purpose schematic-driven design framework that provides easy access to statistical performance techniques. By introducing a novel method that allows for the identification of critical light paths and applying automated phase compensation inside the models, the analysis of fabrication tolerances on-wafer and between wafers is significantly simplified. We demonstrate its application in several PIC designs including complex photonics-based neural networks.
