A new slant on photonic crystal fibers
Optics Express, 2004 We present the novel use of microstructured optical fibers not as 'light-pipes', but in a transverse geometry to manipulate the light propagating across the fiber. Fundamental and higher-order bandgaps were observed experimentally in this geometry using a number of techniques.

D-Shaped Photonic Crystal Fiber Toxic Metal Ions (Arsenic) Sensor Based on Surface Plasmon Resonance
Iraqi Journal of Physics, 2023 In this work, a Photonic Crystal Fiber (PCF) sensor based on the Surface Plasmon Resonance (SPR) technology was proposed. A thin layer of gold (Au) was deposited on a D-shaped Photonic Crystal Fiber (PCF), which was coated with plasmonic chemically ...

Modeling photonic crystal fibers
Advances in Applied Mathematics, 2006 The problem indicated in the title gives rise to a Maxwell problem. However, looking for guided waves in the \(x_3\)-direction and assuming the medium to be \(x_3\)-independent, the author is left with two scalar problems with periodic coefficients. The corresponding Green integral operators and their spectral properties are used for a characterization
