报道了利用保偏光子晶体光纤在1.6μm区域产生超连续谱通过将光参量放大器产生的中心波长为1.5938μm、重复频率为250kHz、脉冲宽度为250fs的光脉冲耦合进纤芯直径为2.0μm、长度为0.2m的保偏光子晶体光纤,获得了1.6μm区域的光谱展宽,展宽的光谱带宽为45.8nm(1.5892～1.6350μm)
It has been reported that supercontinuum generation in a 1.6 μm region by a polarization maintaining photonic crystal fiber is achieved by coupling an optical pulse with a center wavelength of 1.5938 μm, a repetition frequency of 250 kHz and a pulse width of 250 fs into an optical fiber with a core diameter of 2.0 μm, The polarization-maintaining photonic crystal fiber with a length of 0.2m obtains a spectral broadening in the region of 1.6μm with a broadened spectral bandwidth of 45.8nm (1.5892 ~ 1.6350μm)
