Abstract
This paper presents and introduces the fundamentals of physical models of nano-photonic bandgap and numerical methods for design and simulation of different integrated devices. The photonic bandgap nano-structure or crystal provides promising flexibility and easy control over the photonic bandgap properties of waveguide compared with the electronic properties of semiconductors. The nano-fabrication techniques of nano-photonic crystal and nano-structures are highlighted with high potential applications in new generation telecommunication integrated optical devices and biophotonic devices. The nano-photonic bandgap technology is expected to play an even greater role of nano-technology in the 21st century, particularly in the optical-communication industry, optical computation and biomedical photonic devices where many problems that currently constrain the integration technology of optical devices and systems could be addressed.
