“…The rod represented by the solid cylinders corresponding to (SiO 2 /TiO 2 or SiO 2 /ZrO 2 ) material of low refractive index which varied in the range of 1.51 to 1.58 at λ = 1.55 µm. We can produce rods of the refractive index which is within the range from the refractive index of pure silica (N = 1.4) to the refractive index of titania (N = 2.3) [16,17]. The rods of low refractive indexes afford the possibility to produce planar systems, which are compatible with optical telecommunication.…”

Quality factor of two-dimensional photonic crystals microcavity fabricated by SiO2/ZrO2 or SiO2/TiO2 in which the refractive index varied in the range of 1.51 to 1.58 has been investigated in the present paper. The structure studied consists of circular rods of radius r embedded in air slab, while a is the constant of triangular lattice. Finite difference time domain method with perfectly matched layers was used to calculate the transmission spectrum by FullWAVE software. The results of simulation clearly demonstrate the existences of resonance wavelength of which the position and the highest Q (Q ≈ 4 × 10 5 ) value are strongly affected by refractive index. We demonstrate that the calculated Q factor for the designed cavity increases by a factor of three relative for a cavity without increasing the refractive index.

In this work, we theoretically study the use of magneto-photonic crystal for amplication of the magnetooptical eects, to improve the merit factor. A two dimensional magneto-photonic waveguide device, formed by a triangular lattice of air holes, embedded in SiO2/ZrO2 matrix doped with magnetic nanoparticles, is used to study the inuence of the volume fraction (VF %) on the mode conversion. We have used the beam propagation method (BPM) to simulate the eciency coecient in a planar 2D magneto-photonic waveguide. The inuence of VF % on propagation length is studied, and an enhancement in Faraday rotation in 2D magneto photonic crystal is achieved, which proves the ability of the structure to produce magneto-photonic crystal isolator.

In this work, we have reported a theoretical study of a magnetic photonic crystal waveguide (also called a magneto photonic crystal waveguide). This structure is formed by a triangular lattice of air holes in a bismuth iron garnet (BIG) film, grown on gallium gadolinium garnet substrates. Nonreciprocal TE-TM mode conversion is caused by the Faraday rotation if the magnetization is aligned along the z-axis, parallel to mode of propagation. The properties of this phenomenon are simulated using the beam propagation method. The conversion output has been simulated, and the Faraday rotation and modal birefringence have been calculated by varying the gyrotropy and the thickness of the BIG film. This magnetic photonic crystal waveguide has the advantage of enhancing Faraday rotation in optical isolators.
