研究目的
To design an octagonal-shaped porous core photonic crystal fiber (PCF) for terahertz applications that ensures low effective material loss, high core power fraction along with flattened dispersion properties.
研究成果
The proposed octagonal-shaped porous core PCF for terahertz applications offers low effective material loss, high core power fraction along with flattened dispersion properties. The design achieves a birefringence of 0.06 at 1.6 THz frequency, a low EML of 0.06 cm-1, a negligible confinement loss of 10-15 cm-1, a flattened dispersion variation of 0.3 ± 0.1 ps/THz/cm, along with a very high core power fraction of 70% for 290 lm core diameter with a core porosity of 80% and a large modal effective area of 4 9 10-6 m2 over a wide range of frequencies.
研究不足
The technical and application constraints of the experiments, as well as potential areas for optimization, are not explicitly mentioned in the paper.
