“…Among the papers published in MPCs properties, there are a number of reports in such structures with defect layers. The properties of the defect modes in different one-dimensional (1D) conventional PC and 1D MPC have been reported by several authors [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34].…”

Transmission properties of one-dimensional lossy photonic crystals composed of negative and positive refractive index layers with one lossless defect layer at the center of the crystal are investigated by the characteristic matrix method. The results show that as the refractive index and thickness of the defect layer increase the frequency of the defect mode decreases. In addition, it is shown that the frequency of the defect mode is sensitive to the incidence angle, polarization and physical properties of the defect layer but it is insensitive to the small lattice loss factor. The height of the defect mode is very sensitive to the loss factor, incidence angle, polarization, refractive index and thickness of the defect layer. It was also shown that the height and the width of the defect mode are affected by the number of the lattice period and the loss factor.The results can lead to designing new types of narrow filter structures and other optical devices. * email address: alireza.aghajamali@fsriau.ac.ir † email address: barati@susc.ac.ir

“…Therefore such periodic structures allow the control of the allowed or suppressed optical modes. The range of potential applications is very generous, including many optical devices, such as optical filters [9,10], waveguides [11,12], optical switches [13], sensors [14], PhC fibers [15], and coupled devices [16]. By tuning the design of the system, such as refractive index, lattice constant and sample thickness, various heterostructures can be achieved which tailor the optical response of these structures.…”

“…On the other hand, if the periodicity of the PC structure is broken (i.e., by adding a layer with different optical or physical properties), highly localized transmittance states appear inside the photonic band gap, 5 which can be employed to optical filtering. 6,7 Recently, much attention has been paid to the PC structures of different materials that their optical properties can be tuned externally. 7,8 Plasma PCs (PPCs) are a new type of photonic crystals with a periodic array composed of alternating thin un-magnetized or magnetized plasmas and dielectric materials.…”

A one dimensional plasma photonic crystal (1DPPC) structure was proposed to design a tunable compressing/broadening multi-channel optical filter with external controllability. The 1DPPC with arrangement of (AP) n D(PA) n , where A and D are the dielectric materials, P is a magnetized plasma layer and n is the number of the periodicity, was proposed. The well-known transfer matrix method was employed for analysis. In linear transmittance spectrum, n À 1 defect modes were appeared inside the photonic band gap. The results were shown that by increasing the applied magnetic field intensity and its direction, a red-shift and blue-shift were, respectively, observed in defect mode frequencies. On the other hand, the modes were compressed and broadened with increasing the intensity and the direction of the applied magnetic field, respectively. Externally controllable defect modes can be useful in designing a multichannel tunable optical filter. V C 2015 AIP Publishing LLC.
