Design and Optimization of Photonic Crystal Triplexer for Optical Networks

Photonic Crystals (PhCs), also known as Photonic Band-Gap (PBG) materials, can control the spontaneous emission and the propagation of Electro-Magnetic (EM) waves. Due to existence of PBG, PhCs have applications in different areas of optical engineering such as optical filters, switches, power splitters, and demultiplexers which may ultimately pave the way for Photonic Integrated Circuits (PICs). By engineering the photonic band gap, the confinement of light in given wavelengths can be tuned. It means that, the authors can control the transmittance and reflectance wavelengths interval by adjusting the band-gap of each PhC structure.
