WebIntroduction Great interest has recently been shown for photonic bandgap (PBG) fibers that carry most of the field intensity in an air (or hollow) core [1-3]. The reason for this interest in air-guiding PBG fibers is their potential of alleviating a number of barriers of conventional optical fibers in terms of attenuation, non-linearities and ... WebApr 11, 2024 · The theoretical results reveal that defect modes can be generated both periodically and continuously along specific spectral lines inside the photonic bandgap (PBG). This paper reports, for the first time, a robust spectral behavior of induced defect modes, which is directly related to the geometric-phase character of CLC helices …
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. WebPhotonic liquid crystal fibers (PLCFs) define a new class of optical waveguides that combines unique properties of microstructured photonic crystal fibers and liquid crystals. Current progress of research in the field of PLCFs means that a new class of emerging photonics devices can be expected, i.e. tunable attenuators, tunable broad-band filters, …
