Abstract

This study presents a comparative analysis of DFB lasers based on AlGaInAs/InP heterostructures, exploring the impact of different groove shapes and cavity lengths on laser output characteristics. Leveraging the vertical groove structure, we achieved a remarkable laser output of 90mW at 25°C. Compared to lasers without grooves, this represents a 3.6-fold increase in output power, coupled with an impressively low threshold current of only 4mA. In addition, we conducted a study on the temperature stability of the laser, revealing that even at elevated temperatures of 85°C, the laser maintains an edge mode suppression ratio of over 45dB. This demonstrates the robustness and reliability of the laser over a wide range of operating conditions, further enhancing its suitability for practical applications in diverse environments. Upon packaging the chip into a butterfly shape, we observed a significant reduction in relative intensity noise, with values below -162.8 dB/Hz across the frequency range of 0-40 GHz, while operating at an output power of 3mW. These findings underscore the robustness, reliability, and high-performance capabilities of the developed DFB laser, highlighting its potential for various practical applications.

超低 RIN、低阈值 AlGaInAs/InP BH-DFB 激光器

本研究对基于 AlGaInAs/InP 异质结构的 DFB 激光器进行了比较分析，探讨了不同沟槽形状和腔长对激光输出特性的影响。利用垂直凹槽结构，我们在 25°C 时实现了 90mW 的出色激光输出。与没有凹槽的激光器相比，输出功率提高了 3.6 倍，而且阈值电流仅为 4 毫安，令人印象深刻。此外，我们还对激光器的温度稳定性进行了研究，结果表明，即使在 85°C 的高温下，激光器也能保持超过 45dB 的边缘模式抑制比。这证明了该激光器在各种工作条件下的稳健性和可靠性，进一步提高了其在各种环境中的实际应用。将芯片封装成蝶形后，我们观察到相对强度噪声显著降低，在 0-40 GHz 的频率范围内，噪声值低于 -162.8 dB/Hz，同时输出功率为 3mW。这些发现凸显了所开发的 DFB 激光器的坚固性、可靠性和高性能，突出了其在各种实际应用中的潜力。

期刊介绍： Rapid progress in optics and photonics has broadened its application enormously into many branches, including information and communication technology, security, sensing, bio- and medical sciences, healthcare and chemistry. Recent achievements in other sciences have allowed continual discovery of new natural mysteries and formulation of challenging goals for optics that require further development of modern concepts and running fundamental research. The Journal of the European Optical Society – Rapid Publications (JEOS:RP) aims to tackle all of the aforementioned points in the form of prompt, scientific, high-quality communications that report on the latest findings. It presents emerging technologies and outlining strategic goals in optics and photonics. The journal covers both fundamental and applied topics, including but not limited to: Classical and quantum optics Light/matter interaction Optical communication Micro- and nanooptics Nonlinear optical phenomena Optical materials Optical metrology Optical spectroscopy Colour research Nano and metamaterials Modern photonics technology Optical engineering, design and instrumentation Optical applications in bio-physics and medicine Interdisciplinary fields using photonics, such as in energy, climate change and cultural heritage The journal aims to provide readers with recent and important achievements in optics/photonics and, as its name suggests, it strives for the shortest possible publication time.
