Time-domain dynamic electric field distribution of low-oscillation sculptured structure dispersive mirrors

In order to effectively address the issues of signal distortion and attenuation resulting from dispersion effects in modernday communication system. A new dispersion-compensating concentric core photonic crystal fiber (PCF) is presented and analyzed, using finite element method (FEM). The simulation results indicate that by maintaining the structural parameters of this PCF at a large hole diameter of 1.60μm, a small hole diameter of 0.50μm, a central hole diameter of 0.80μm, and a lattice constant of 2.00μm constant, adjusting the refractive index of the index-matching fluid from 1.417 to 1.423 can result in negative dispersion values ranging from -2049.3 to -9893.6ps/nm/km. This refractive index tuning allows the proposed PCF to effectively compensate dispersion within the 1.4-1.7μm wavelength range. The proposed PCF maintains low CL throughout the compensation process, ranging from 10 -8 dB/m to 10 -6 dB/m. Moreover, the proposed PCF demonstrates a high linearity relationship of 0.99426 between the refractive index of the index-matching fluid and the phase-matched wavelength. This PCF holds significant prospect for modern large-scale high-speed communication systems.
