摘要

具有光子-光子共振（PPR）的 InP 膜直接调制半导体激光器（DML）因其占地面积小、能量效率高和调制带宽高而在短程电信系统中具有很大的应用潜力。然而，基于 PPR 的器件中 S21 响应的稳定性对激光模式和 PPR 模式之间的精确相位匹配非常敏感。我们设计、制造、测量并分析了一种 C 波段 DML，它通过长无源波导顶部的热移相器实现主动相位调整。移相器可在 5 GHz 范围内调整 PPR 频率，从而使 PPR 峰值功率增强 16 dB。我们对偏置电流和移相器电流不同组合下的小信号响应进行了研究，结果表明，在某些情况下，移相器可以实现扫频偏置电流无法达到的带宽。对激光器的动态行为进行了模拟，并详细研究了最重要的设计和加工参数对带宽的影响。

C-Band Directly Modulated Lasers With Tunable Photon–Photon Resonance in InP Membrane

InP membrane directly modulated semiconductor lasers (DMLs) with photon-photon resonance (PPR) have a lot of potential to be used in short-range telecommunication systems due to their small footprint, high energy efficiency, and high modulation bandwidth. However, the stability of the S21 response in PPR-based devices is sensitive to precise phase-matching between the lasing mode and PPR mode. We designed, fabricated, measured, and analyzed a C-band DML with active phase-tuning achieved by a thermal phase shifter on top of a long passive waveguide. The phase shifter enables tuning of the PPR frequency in the range of 5 GHz resulting in the PPR peak power enhancement of 16 dB. We study the small-signal responses at different combinations of bias current and phase shifter current and show, that in some cases the phase shifter enables a bandwidth that cannot be achieved by sweeping the bias current. The laser dynamic behavior is simulated and the influence of the most important design and processing parameters on bandwidth is studied in detail.

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.
