Bandwidth optimization of single-polarization single-mode photonic crystal fibers
We present an algorithm for computing single-polarization single-mode (SPSM) photonic crystal fibers with optimal bandwidth. Our approach is a topology optimization strategy based on convex conic optimization combined with a subspace method. The original problem of maximizing the bandwidth between the fundamental guided mode and the higher order unguided modes is reformulated as a problem of op...
متن کاملHydrophobic photonic crystal fibers.
We propose and demonstrate hydrophobic photonic crystal fibers (PCFs). A chemical surface treatment for making PCFs hydrophobic is introduced. This repels water from the holes of PCFs, so that their optical properties remain unchanged even when they are immersed in water. The combination of a hollow core and a water-repellent inner surface of the hydrophobic PCF provides an ultracompact dissolv...
متن کاملPhotonic Crystal Fibers
Photonic crystal fibers are a new class of optical fibers. Their artificial crystal-like microstructure results in a number of unusual properties. They can guide light not only through a well-known total internal reflection mechanism but using also photonic bandgap effect. In this paper different properties possible to obtain in photonic crystal fibers are reviewed. Fabrication and modeling met...
متن کاملInvestigation of Scalar Modulation Instability in the Presence of Raman Scattering in Photonic Crystal Fibers
In this paper, by including Raman scattering in the coupled-mode equations, the scalar modulation instability in photonic crystal fibers is investigated. The evolution of the pump, Stokes and anti-Stokes waves along the fiber as well as the conversion efficiency for two cases, with and without Raman effect, are studied. The effect of anti-Stokes seed and the pump depletion on the evolution of S...
متن کاملTwo-mode photonic crystal fibers.
Index-guiding photonic crystal fibers with appropriate structural parameters support the fundamental and second order modes over a practically infinite wavelength range. The polarization principal axes and mode field patterns of the modes can be made stable by having different size air-holes along the orthogonal directions. The potential applications of such two-mode PCFs are discussed.
