Abstract

Complex coupled distributed feedback (DFB) lasers and sampled grating distributed Bragg reflector (SGDBR) lasers under optical injection locking are investigated to determine lowest noise operation. A noise reduction (frequency and intensity combined) of up to 15 dB was measured utilizing detuned optical injection locking at the relaxation oscillation frequency. Furthermore, 4 dB improvement in frequency noise at 10 kHz offset for higher coupling coefficient DFBs under injection locking was measured. The DFB lasers show more sensitivity to injection locking and have a lower need of injection power while exhibiting better signal to noise ratio compared to an SGDBR.

最大限度降低光注入锁定下分布式反射激光器类型的噪声

研究了光注入锁定下的复杂耦合分布式反馈（DFB）激光器和采样光栅分布式布拉格反射器（SGDBR）激光器，以确定最低工作噪声。通过在弛豫振荡频率上使用失谐光注入锁定，测得噪声（频率和强度组合）降低达 15 分贝。此外，在注入锁定条件下，测量到耦合系数较高的 DFB 在 10 kHz 偏移时的频率噪声降低了 4 分贝。与 SGDBR 相比，DFB 激光器对注入锁定的敏感度更高，对注入功率的需求更低，信噪比更高。

期刊介绍： The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
