This book investigates the nonlinear optical applications by using stripe and rod shaped resonant photonic nanoantennas on chalcogenide glasses. This work includes theoretical background about how nanoantennas focus light on a substrate and mentions on nonlinear interaction of focused light with chalcogenide glass. It explains how to design a nanoantenna to focus light on a specified substrate by engineering shape and size of the antenna according to refractive indexes of the antenna and the substrate material. Details of design and simulation parameters are also given. Not only design of the...
