Did you know?
WebIn case of a hollow core fiber, the principles of guidance rely on Photonic Band Gap (PBG) guidance, or on guidance for Antiresonant Reflecting Optical Waveguide (Arrow) (Russell, 2003). Because of their microstructured nature, microstructured fibers present a unique versatility for tuning their guidance characteristics and their properties. WebApr 13, 2000 · The complete PBG persists from 0.158 a /λ to 0.190 a /λ in all directions for the first bandgap. A higher-order bandgap is also seen from 0.408 a /λ to 0.418 a /λ . The …
