All-optical logical operation in photonic wire nano-cavities

Abstract

One of the major topics of interest in recent research on photonics is the study and development of photonic structures for fast signal processing signal for telecom applications. These kinds of structures are required to be compact and compatible with monolithic integration into one CMOS chip. The combination of one-dimensional photonic crystal structures with narrow waveguides in high refractive index contrast materials such as silicon-on insulator (SOI) can satisfy all the requirements.
