We propose a novel photonic crystal slab waveguide that provides a single-mode band with large bandwidth. The proposed

waveguide is obtained by introducing a line defect in a triangular lattice of air holes in a ...

در این مقاله به طراحی یک موجبر بلور فوتونی با پاشندگی سرعت گروه صفر برای انتشار نور کند می پردازیم. به این منظور به جستجوی باندهای فرکانسی می رویم که در آنها ضریب گروه نسبت به فرکانس تقریبا ثابت است و به آنها نواحی تخت ...

In this paper, a 60o waveguide bend is designed in a two-dimensional (2D) photonic crystal (PC) slab to provide high transmission over a large bandwidth. We apply geometrical modification in the bend region to improve the ...

We investigate a photonic crystal waveguide coupler which is formed by two closely-spaced linear waveguides in a two-dimensional triangular lattice of air holes. Our study show that shifting one row of the air holes between ...

In this paper, we design a waveguide on photonic crystal slab for propagation of low-dispersion slow light. By shifting the air holes adjacent to the waveguide, we obtain a photonic crystal waveguide with a group index of ...

In this paper, we investigate coupling of light to slow modes in a photonic crystal power splitter composed of a Y-junction and two 608 bends. First, a combination of two cascaded bends which is commonly used in integrated ...
