The resonant tunneling diode (RTD) is a semiconductor device that can act as the highest speed electronic amplifier and oscillator (bandwidth >1 THz). It is made using ultrathin (<10 nm) layers of semiconductor alloy that can be easily integrated with photonic devices such photodetectors and lasers. Incorporating the ultrahigh speed RTD amplifier gives the photonic devices new capabilities that are described in the book - as are exciting new applications made possible by integrating the RTD with photonic devices such as neuromorphic (brain-like) photonic computing. Some of these systems provide real-world applications of concepts from nonlinear dynamical theory - concepts including excitability, chaos and synchronisation. Key Features: Comprehensive introduction to the research literature on resonant tunnelling diode photonics State of the art introduction into how this technology is deployed to make devices for various systems Software –Python notebooks which give the reader not only insight into how existing devices operate but also tools that can be used to design new devices Unique and cogent combination of fundamental physical principles and applications of resonant tunnelling diode photonics

This book brings together two broad themes that have generated a great deal of interest and excitement in the scientific and technical community in the last 100 years or so: quantum tunnelling and nonlinear dynamical systems. It applies these themes to nanostructured solid state heterostructures operating at room temperature to gain insight into novel photonic devices, systems and applications.
