In this paper, designs of optical filters are demonstrated by using double defect layered 1D
ternary photonic band gap (PBG) structures. The wavelength of light to be filtered by this …

In this paper, a Y-shaped power splitter based on a two dimensional photonic crystal (PhC)
for TE modes is designed and optimized. A triangular lattice of air holes is used for Y-shaped …

In this study, we propose a new type of photonic crystal band-pass and band-stop filter
based on biperiodic structure. Usually two types of photonic crystal band-pass filters are …

In this note, design of an optical filter is demonstrated by using double defect layered 1D
quaternary photonic band gap (PBG) structure. This structure filters 1403 nm wavelength of …

In this paper, we propose the time-dependent coupled mode analysis of one-dimensional
magneto-photonic crystals including one, two or multiple defect layers. The performance of …

In this paper, we present two new photonic crystal designs, giving the free space of the slabs
around the cavities as well as the possibility of further absorption for the active layer of …

Abstract “Photonic Crystals (PCs)” are dielectric structures with periodic spatial alternations
of refractive index on the scale of the wavelength of light. Many optical devices, based on …

We present 2-, 3-, and 6-way optical demultiplexer and optical filters based on coupled
waveguide and photonic crystal cavities. Demultiplexers with 3 nm channel separation and …

In this paper, a new 2-D frequency converter based on second harmonic generation (SHG)
in GaAs photonic crystal waveguides is proposed. The input waveguide, where the second …

In the present analysis we have investigated the photonic crystal waveguide (PCW) based Y-
junction splitter through three dimensional finite difference time domain simulation methods …
