WebI used a 2um uniform PML around the honey-comb PCF, with scaling factor equal 1 and curvature equal 2. The only things I changed were the type of the PML from cartesian to … A step-index fiber guides light through the high refractive index of the core, while a photonic crystal fiber (PCF) is made up of microstructured optical fibers that guide light either through index guiding or band gap confinement. In this blog post, we focus on index-guided PCF, where the core of the PCF is made of … See more Photonic crystals are optical structures that periodically repeat to achieve different applications, such as bending light, filtering, and mirrors. One of the simplest configurations of a photonic crystal is to set up two different … See more When GaAs pillars are arranged in a periodic manner, as shown in the figure below, the device has the ability to bend light with an angle (90° in this case) and also act as a filter for … See more There are different approaches to modeling photonic crystal devices, whether you perform a parametric sweep of different frequencies, analyze the modes, or solve for … See more An alternate approach to modeling the band gap is to formulate an eigenvalue problem, as shown in the Band Gap Analysis of a Photonic … See more WebJan 20, 2024 · What is progressive multifocal leukoencephalopathy? Progressive multifocal leukoencephalopathy (PML) is a disease of the white matter of the brain, caused by a virus infection (polyomavirus JC) that targets cells that make myelin—the material that insulates nerve cells (neurons). people growers
