| 摘 要： | 通过实验研究了一种光子晶体光纤环形移频器,该移频器基于布里渊频移原理,利用光子晶体光纤布里渊增益高、阈值低的特点,同时利用光纤环形腔选频放大技术获得窄线宽高增益激光输出。实验结果表明:在波长为1 548 nm单纵模光纤激光泵浦下,10 m长光子晶体光纤的受激布里渊散射阈值功率约为457mW,环形腔输出的受激布里渊散射Stokes光相对于入射光移频量为9.778GHz、线宽500 kHz,并且移频量可以通过温度进行微调。该移频器可以用于分布式光纤布里渊传感器和微波发生器。

| Abstract: | A ring frequency shifter based on the photonic crystal fiber was proposed.Based on Brillouin frequency shift theory,the frequency shifter could achieve a narrow linewidth and high-gain laser output for the photonic crystal fiber which had high Brillouin gain and low threshold,using the frequency selecting amplification technology of fiber optic ring resonator.The experiment results show that the threshold power of stimulated Brillouin scattering(SBS) of photonic crystal fiber is 457 mW,the frequency shift of stimulated Brillouin scattering wave compared with the incident light is 9.778 GHz with linewidth less than 500 kHz,the frequency shift can be finely adjusted by temperature.The frequency shifter can be applied in the distributed fiber optic Brillouin sensor and microwave generator. |
