WebWe propose a novel design of photonic crystal fiber to achieve the single-polarization single-mode transmission. The topology of this design only employs, with a view of simplicity and stability, uniformly sized circular air holes, and they are all regularly latticed in a pure-silica background. Guiding properties are studied by use of the full-vector finite element … WebJun 2, 2024 · Chiral liquid crystal materials that are responsive to environmental stimuli are in demand.
