ABSTRACT
Optical and photonic materials and structures have long been significantly devoted to optical signal transmission, storage, and processing in the optoelectronic community. Photonic integration technologies have been more advanced since the appearance of nanophotonic materials such as surface plasmon and negative refractive index material. This chapter describes nanooptical nonlinearity (ONL) represented by quantum dot (QD) ensemble is a key element of the Photonic Crystal (PC)-based all-optical switch, while surface plasmon and negative index material structures have potential to enhance the ONL of the QD via optical nano-dipole antenna and strong optical localization in nanostructures. It discusses state-of-the-art technologies and applications of these nanophotonics. For generic applications, design of the two-dimensional-PC waveguide with a wide bandwidth and transmission spectrum close to the design is important. Photonic integrated circuits involving optical nonlinear QDs acting as gain and modulation media extend their applicability to devices essential for future telecommunication network systems.
