Abstract
High power, compact, red edge-emitting lasers based on GaInP quantum wells are desirable for applications such as laser display technologies or two-photon upconversion. Here, we investigate the influence of passivation methods on the performance of 635 nm ridge waveguide lasers. We demonstrate that vacuum cleaving results in a higher facet stability compared to hydrogen cleaning, resulting in a reliable output power for 7.5 μm wide emitters of 200 mW for one week and 160 mW for 2000 hours. Moreover, our investigation shows that it is essential to consider the thermal budget of passivation methods for the optimization of the laser performance of phosphide-based lasers.
期刊介绍：
Breakthroughs in the generation of light and in its control and utilization have given rise to the field of Photonics, a rapidly expanding area of science and technology with major technological and economic impact. Photonics integrates quantum electronics and optics to accelerate progress in the generation of novel photon sources and in their utilization in emerging applications at the micro and nano scales spanning from the far-infrared/THz to the x-ray region of the electromagnetic spectrum. IEEE Photonics Journal is an online-only journal dedicated to the rapid disclosure of top-quality peer-reviewed research at the forefront of all areas of photonics. Contributions addressing issues ranging from fundamental understanding to emerging technologies and applications are within the scope of the Journal. The Journal includes topics in: Photon sources from far infrared to X-rays, Photonics materials and engineered photonic structures, Integrated optics and optoelectronic, Ultrafast, attosecond, high field and short wavelength photonics, Biophotonics, including DNA photonics, Nanophotonics, Magnetophotonics, Fundamentals of light propagation and interaction; nonlinear effects, Optical data storage, Fiber optics and optical communications devices, systems, and technologies, Micro Opto Electro Mechanical Systems (MOEMS), Microwave photonics, Optical Sensors.
