摘要
可调谐激光源在硅基光芯片筛选、激光雷达,以及智能传感领域有着重要应用价值,其中O波段可调谐激光源尤其适用于数据中心高速互联场景。基于外腔反馈的机械式可调谐激光源是一种突破单片集成式半导体激光源调谐范围限制进而有效扩展其调谐范围的有效技术手段。研制了3台O波段可调谐激光源,利用增益芯片作为种子源,通过闪耀光栅将满足光栅方程的激光光束反馈至增益芯片增益区,实现了约100 nm调谐范围、优于±1.6 pm绝对波长精度、优于0.2 pm/1 h波长稳定性和优于0.0020 dB/1 h功率稳定性的输出结果,并对其长期输出一致性进行了研究。结果表明,凭借精密谐振腔体模块和波长锁定模块的优异特性,实现高可复现性的O波段可调谐激光输出将具有巨大潜力。
The tunable laser sources play a crucial role in silicon-based optical chip screening,laser radar and intelligent sensing system with O-band tunable laser sources being particularly suitable for high-speed data center interconnections.The mechanical tunable laser source based on external-cavity feedback is an effective technical means to break through the limitation of the limited tuning range of the monolithically integrated diode laser source and effectively expand its tuning range.Three O-band tunable laser sources are developed,using the gain chip as the seed source,and feeds the laser beam satisfying the grating equation to the gain region of the gain chip through the blazed grating,and achieves the output results of about 100 nm tuning range with outstanding performance,absolute wavelength accuracy better than±1.6 pm,wavelength stability better than 0.2 pm/1 h and power stability output better than 0.0020 dB/1 h,and the long-term output consistency is studied.The results show that with the excellent characteristics of the precision resonant cavity module and the wavelength locking module,there is great potential to achieve highly reproducible O-band tunable laser output.
