Abstract

We demonstrate a III-V/Si widely wavelength tunable laser covering the entire L-band for the optical communication systems. By carefully designing the silicon ring filter, low threshold current and high output power are expected. Using the standard silicon photonic process, the silicon filter chip is fabricated and compactly packaged with a reflective semiconductor optical amplifier. The low threshold current of 20 mA is achieved at 15 °C, and over 76 mW output power is obtained at 320 mA. The wavelength tuning range from 1565 nm to 1635 nm is realized with the side-mode suppression ratio larger than 50 dB. Furthermore, the intrinsic linewidth narrower than 25 kHz and relative intensity noise below −152 dB/Hz is achieved, which can support the coherent communications.

l波段应用的高功率III-V /Si集成波长可调谐激光器

我们展示了用于光通信系统的覆盖整个L波段的III-V/Si宽波长可调谐激光器。通过仔细设计硅环形滤波器，可以获得低阈值电流和高输出功率。采用标准的硅光子工艺，制作了硅滤波器芯片，并用反射半导体光放大器进行了紧凑封装。在15°C下可获得20 mA的低阈值电流，在320 mA下可获得超过76 mW的输出功率。实现了1565 nm至1635 nm的波长调谐范围，侧模抑制率大于50 dB。此外，本征线宽小于25kHz，相对强度噪声低于-152dB/Hz，可以支持相干通信。

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.
