摘要:
In view of dispersion compensating in multiple wavebands at the same time,this paper proposes a novel multi-waveband dispersion compensating fiber (DCF) based on hybrid photonic crystal fiber (PCF).The proposed fiber can compensate multiple wavebands at the same time.The mechanism of the multi-waveband dispersion compensation is analyzed,and the different material-filled structure is discussed numerically.The simulation results show that the multi-waveband DCF can compensate multiple wavelengths at the same time.By a reasonable design,this fiber can replace the multi-dispersion compensating system composed by cascaded multiple devices,and minimize the loads of the system in an efficient way.
