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...
