چکیده
In this paper, the optical properties of the multilayer rugate filter by structure of (HL) ^ 9Hhas been investigated. Here the reflection, optical density and electric field strength of designed filter by using four materials of Ta2O2, Nb2O5 and ZnS as the materials with high refractive indexandSiO2as a material with low refractive index are compared with each other. Finally, it is realized that the bandwidth of the reflection and the optical density of the structures (ZrO2-SiO2) ^ 9ZrO2, (Nb2O5-SiO2) ^ 9Nb2O5, (Ta2O5-SiO2) ^ 9Ta2O5and(TiO2-SiO2) ^ 9TiO2 increase respectively and the electric field strength reduces.

In this paper, we proposed a novel structure for designing all optical filter based on photonic crystal structure. In designing the proposed filter, we simply employed a point defect localized between input and output waveguides as wavelength selecting part of the filter. The initial form of this filter is capable of selecting optical waves at =1560 nm, the transmission efficiency of the filte...

ZnO nanorods with various aspect ratios (by changing the time of growth between 0-240 min) were synthesized using hydrothermal method and were investigated using XRD, SEM, UV–Vis and PL. It was found that growth time is directly coupled with the length, orientation and aspect ratio of the nanorod arrays. The optical transmittance of the NR arrays indicated a regular decrement of average transmi...

An electro-optic tunable single and multi-channel optical filter based on one-dimensional defective photonic crystal (1DDPC) structure is proposed. A couple of externally tunable defects in arrangement of (AB)5D1(BA)D2(BA)5, where A and B are dielectric materials, D1 and D2 are the tunable defects are used. The defects are composed of the ferroelectric LiNbO3 crystals and two pairs of thin Ag l...
