Introduction to Layout Design and Automation of Photonic Integrated Circuits

This book introduces readers to the physical design (layout) and design automation of Photonic Integrated Ciruicts (PICs) which is an essential building block of Electronic-Photonic Design Automation (EPDA). Proper PIC design automation and implementation of complex curvilinear shapes play a critical role in reliability, quality, and time-to-market of complex PIC products. The author starts by introducing some basic mathematical concepts used in implementation of photonic components, followed by a deep dive into implementation details of parameterized PIC components. The book introduces the industry-standard schematic driven layout flow and tries to simplify the concepts and implementations. The author conveys difficult concepts and advanced EPDA scripting/programming methodologies, using a simple language and coding examples. 1 Preface References Acknowledgments Disclaimer Contents List of Figures List of Codes 978-3-031-25288-4_1 1 Curves Implementation 1.1 Curves 1.2 Parametric Curves 1.3 Case Study 1.4 Curve Stitching 1.5 Case Study 978-3-031-25288-4_2 2 Path Implementation 2.1 Paths 2.2 Implement a Uniform ccPath 2.3 Implementation of a Non-uniform Path 2.4 ccFacet Objects 2.5 Preserve Facet Objects 2.6 Generate General Waveguide Shapes Using ccGenOffsetFig 2.6.1 Waveguide Template 978-3-031-25288-4_3 3 Surface Implementation 3.1 Surfaces 3.2 ccSurface Use Cases 3.2.1 Donut/Ring Shape 3.2.2 Pie Shape 3.3 Boolean Operation 3.4 Asymmetric Taper 978-3-031-25288-4_4 4 Parameterized Cells (PCells) 4.1 Introduction 4.2 PCell Implementation Structure 4.3 Enable Connectivity and Hierarchical Design 4.4 Create Optical Port in Layout 4.5 Create Optical Port for a Symbol 4.6 Component Description Format (CDF) 4.6.1 Callbacks 4.7 Schematic Driven Layout (SDL) Methodology 978-3-031-25288-4_5 5 Introduction to Design Implementation Using Scripting [DELETE] 5.1 Create an Instance 5.2 Establish Connectivity 5.3 Creating Terminals and Pins for Hierarchical Design Use 978-3-031-25288-4_6 6 Introduction to Software Development and General Scripting [DELETE] 6.1 Orientation Matching Between Schematic and Layout 6.2 Instance Chaining 6.3 Extract Connectivity Based on Physical Proximity 6.3.1 Pin Figures Proximity Sort 6.3.2 Connectivity Graph 6.4 Closure
