摘要:
A simple design procedure is used to generate photonic crystal fibers (PCFs) with ultra-flattened chromatic dispersion.Only four parameters are required, which not only considerably saves the computing time,but also distinctly reduces the air-hole quantity.The influence of the air-hole diameters of each ring of hexagonal PCFs (H-PCF, including 1-hole-missing and 7-hole-missing H-PCFs), circular PCFs (C-PCF),square PCFs (S-PCF), and octagonal PCFs (O-PCF) is investigated through simulations.
