Abstract :
We present an algorithm that adapts the mature stack and draw (SaD) methodology for fabricating the exotic equiangular spiral photonic crystal fiber (ES-PCF). The principle of Steiner chains and circle packing is exploited to obtain a nonhexagonal design using a stacking procedure based on hexagonal close packing. The optical properties of the proposed structure are promising for supercontinuum generation. This approach could make accessible not only the equiangular spiral but also other quasi-crystal PCF through SaD.
