Title: "Fabrication tolerance-aware schematic-driven PIC design"

Abstract: 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.

Paper 11690-2: "Schematic-driven PIC design process considering manufacturing tolerances"

Abstract: Inevitable manufacturing tolerances strongly degrade the fabrication yield of photonic integrated circuits (PICs), unless their effect on overall performance characteristics is considered and mitigated during the design process. We present a general purpose schematic-driven design framework that provides easy access to statistical performance techniques such as sensitivity, corner and yield analysis. It supports the analysis of statistical parameter variations due to manufacturing tolerances on-waver and between wavers, and delivers valuable insights into the dependency of structural parameters on the overall PIC performance. We demonstrate its application on complex PIC designs comprising up to hundreds of photonic building blocks.

OIDA Sponsored Webinar:

Automated PIC Modelling: A Photonic Neural Network Use Case

As the complexity of Photonic Integrated Circuits (PICs) continues to grow, testing environments become more complicated. In this webinar, we will present several simulation testbenches prepared for visualizing typical measurement characteristics. The examples we will discuss include methods for group index verification, simulation of passive circuit transfer functions, characterization of SOAs, and evaluating the transfer characteristic of an Activation Unit for a Photonic Neural Network. These examples will all be demonstrated live using the photonic design automation (PDA) software VPIcomponentMaker Photonic Circuits.
