Abstract

The optical negative-feedback laser monolithically integrated on an InP substrate for obtaining narrow linewidth is investigated. Optical negative feedback (ONF) induced by reflection of light from a Fabry-Perot (FP) resonator reduces linewidth of a distributed Bragg reflector (DBR) laser by 1/14 compared to that of a free-running DBR laser. The measured reflectivity of the fabricated ONF laser is compared to reflectivity simulated with an effective reflectivity model. It is demonstrated that control of the feedback phase is necessary to reduce linewidth by exploiting optical negative feedback. Linewidth is expected to be further reduced by using an FP resonator with a higher quality factor. It is also demonstrated that ONF lasers are compatible with fabrication in the InP foundry platform.

单片集成窄线宽光负反馈激光器

研究了单片集成在InP衬底上的窄线宽光负反馈激光器。由Fabry-Perot （FP）谐振腔光反射引起的光负反馈（ONF）使分布式布拉格反射器（DBR）激光器的线宽比自由运行的DBR激光器的线宽减小了1/14。将制备的ONF激光器的实测反射率与用有效反射率模型模拟的反射率进行了比较。研究表明，为了利用光负反馈减小线宽，需要控制反馈相位。通过使用具有更高质量因数的FP谐振器，线宽有望进一步减小。实验还证明了ONF激光器与InP代工平台上的制造是兼容的。

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.
