The Field and Energy Distributions of the Fundamental Mode in the Solid-Core Photonic Crystal Fibers for Different Geometric Parameters

For a solid core photonic crystal fiber with the triangular lattice, the field and energy distributions of fundamental mode are considered at 1.55  μm wavelength. The silica core is constituted by removing the 7 air holes. The cladding consists of the two-dimensional silica-air photonic crystal with the 4 rings of air holes. The field and energy distributions were investigated for three different values of . Here, d and represent the diameter of air holes and the pitch length, respectively. The simulations show that, for the fixed , the increase in ratio does not cause the considerable changes in the field and energy intensity distributions, but for the fixed , the increase in this ratio affects the intensity distributions reasonably.
