Broadband ultra-flattened dispersion, ultra-low confinement loss and large effective mode area in an octagonal photonic quasi-crystal fiber.
TL;DR: The robustness of optical properties including dispersion, confinement loss, and effective mode area in this PQF is discussed, assuming a deviation ±3% of all air holes.
Journal ArticleDOI
Refractive index sensing characteristics in a D-shaped photonic quasi-crystal fiber sensor based on surface plasmon resonance.
Chenguang Li,Bei Yan,Jianjun Liu +2 more
TL;DR: A D-shaped photonic quasi-crystal fiber (PQF) sensor based on surface plasmon resonance is proposed for refractive index (RI) sensing that realizes the high-sensitivity sensing in the near-infrared band.
Journal ArticleDOI
Polarization filtering in the visible wavelength range using surface plasmon resonance and a sunflower-type photonic quasi-crystal fiber
TL;DR: In this article, a novel polarization filter based on a sunflower-type photonic quasi-crystal fiber (PQF) is proposed, which can efficiently produce polarized light with visible wavelengths by using the resonance between the second-order surface plasmon polariton mode and the core mode of the PQF.
Journal ArticleDOI
Robust transmission of orbital angular momentum mode based on a dual-cladding photonic quasi-crystal fiber
Journal ArticleDOI
Topological Edge State in the Two-Dimensional Stampfli-Triangle Photonic Crystals
TL;DR: In this paper, the relationship between topological properties and structural parameters is revealed, and how to make optical topological insulators with better adjustability by changing only the diameter of the cylinders in the basic structural unit of the photonic crystal.
