摘要
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)
The generation of supercontinuum in the 1.6 μm region was reported in a polarization-maintaining photonic crystal fiber.The optical pulses produced by optical parameter amplifier (OPA) with the central wavelength of 1.5938 μm,the repetition rate of 250 kHz,the pulse duration of 250 fs were coupled into a 0.2m-long,polarization-maintaining photonic crystal fiber.The broadened spectrum with the bandwidth of 45.8 nm(1.5892~1.6350 μm) in the 1.6 μm region was obtained.
