Complex-Frequency Excitations in Photonics: From Benjamin Franklin to New Physics

In this presentation at the IEEE RAPID conference, Dr. Alex Krasnok from Florida International University delves into the revolutionary concept of complex frequency excitations in photonics. Starting with a historical perspective that links Benjamin Franklin's contributions to electromagnetism and the acceptance of negative numbers, Dr. Krasnok explores the essential role of complex numbers in quantum mechanics and their application in modern photonics. He demonstrates how complex frequency signals, characterized by exponential growth or decay, offer new ways to analyze and excite scattering systems. Dr. Krasnok presents groundbreaking research on the behavior of poles and zeros in the complex frequency plane, discussing their implications for Hermitian and non-Hermitian systems. The talk also covers recent developments in time-reversed excitation, reflection-less plasma sources, and the use of complex frequency signals in RLC circuits and integrated photonics. Dr. Krasnok's work on visible-invisible pole coupling offers potential solutions to the scalability challenges in quantum computing and optical communications. This comprehensive exploration of complex frequency excitations opens new avenues in photonics, quantum circuits, and beyond, pushing the boundaries of our understanding and technological capabilities.
