摘　　要：扫频连续光源在光纤传感、算力网络与50G PON接入网等领域有广泛应用,为了实现高质量的O波段连续可调谐激射,报道了一种基于Littman-Metcalf反馈结构形式的1310 nm扫频光源。实验采用弯曲波导端反射率0.005%的增益芯片作为内腔增益区,通过外腔反馈技术实现衍射光束的注入锁定。实验结果显示,在500 mA的驱动电流驱动下,可实现的无跳模可调谐输出范围为1270~1350 nm,对应的峰值输出功率为17.98 dBm,扫频功率重复性约为±0.023 dB。Sweep frequency laser source is widely used in optical fiber sensing,computing power network and 50G PON access network,in order to achieve a high quality O-band continuous tunable laser source,the 1310 nm sweep frequency laser source based on Littman-Metcalf feedback configuration is reported.In this experiment,a gain chip with the reflectance of 0.005%of the curved waveguide end is used as the gain area of the inner cavity,the injection locking of the diffractive laser beam is realized through the external-cavity feedback technology.Experimental results show that under the condition of 500 mA injection current,the tunable wavelength range of 1270~1350 nm can be realized with mode-hopping free,the corresponding peak output power is 17.98 dBm,and the sweep power repeatability is about±0.023 dB.
