The emergence of submicorn dimensions and nanostructures in semiconductor
devices has allowed electronic and optoelectronic devices to achieve
impressive performance and fuel the communications revolution. In this
presentation we will focus on how electronic devices are transformed with the
incorporation of advanced materials and nanosctructures. We will discuss
experimental techniques that allow device engineers to design and harvest
nanotechnology effects. Heterojunction Bipolar Transistors (HBTs) with 5 nm
layers, tunnel barriers and a potential to exceed GHz range high-speed
operation will be examined. Finally we will delve into how a textbook quantum
mechanics exercise became an optical modulator and was successfully
implemented in a free space optoelectronic communications system.
