Giant anomalous self-steepening and temporal soliton compression in silicon photonic crystal waveguides

High birefringence and near‐zero dispersion control of nonlinear photonic crystal fibers with a double‐cladded coaxial core

“…For this reason, the PCF provides the distinct feature that can be produced from a single optical material with a periodic array of air holes running along the length of the fiber axis and offers additional advantages such as dispersion tailoring, soliton transmission, supercontinuum generation, and especially unlimited single-mode operation, and so on. 8,9 Conventionally for the purpose of preserving the polarization state, the polarization-maintaining fibers (PMFs) referred to as bow-tie and PANDA fibers have been widely applied with bow-tie and circular shapes, respectively, to provide high levels of stress-induced birefringence. 10,11 Those fibers are constructed by introducing nonsymmetrical stress-applying parts to incorporate photoelastic effect due to two different thermal expansion coefficients, hence requiring a least two isolated optical materials in the fiber claddings.…”

“…Here an artificial photonic crystal can be formed by modulating the relative refractive permittivity of a material with an appropriately‐designed repeating pattern in space. For this reason, the PCF provides the distinct feature that can be produced from a single optical material with a periodic array of air holes running along the length of the fiber axis and offers additional advantages such as dispersion tailoring, soliton transmission, supercontinuum generation, and especially unlimited single‐mode operation, and so on 8,9 …”
