摘要	In accordance with one embodiment of the present disclosure, a process of manufacturing a semiconductor laser diode comprising a gain section, a QWI output window, and QWI waveguide areas is provided. The QWI waveguide areas are fabricated using quantum well intermixing and define a QWI waveguide portion in the QWI output window of the laser diode. The QWI output window is transparent to the lasing wavelength ?L. The QWI waveguide portion in the QWI output window is characterized by an energy bandgap that is larger than an energy bandgap of the gain section such that the band gap wavelength ?QWI in the QWI waveguide portion and the QWI output window is shorter than the lasing wavelength ?L. The QWI output window is characterized by a photoluminescent wavelength ?PL. The manufacturing process comprises a ?PL screening protocol that determines laser diode reliability based on a comparison of the lasing wavelength and the photoluminescent wavelength ?L of the QWI output window. Additional embodiments are disclosed and claimed.
其他摘要	根据本公开的一个实施例，提供了一种制造半导体激光二极管的工艺，该半导体激光二极管包括增益部分，QWI输出窗口和QWI波导区域。 QWI波导区域使用量子阱混合制造，并在激光二极管的QWI输出窗口中定义QWI波导部分。 QWI输出窗口对激光发射波长λL是透明的。 QWI输出窗口中的QWI波导部分的特征在于能带隙大于增益部分的能带隙，使得QWI波导部分和QWI输出窗口中的带隙波长ΔQWI短于激射波长。 ·L。 QWI输出窗口的特征在于光致发光波长λPL。制造过程包括？PL筛选协议，其基于激光波长和QWI输出窗口的光致发光波长λL的比较来确定激光二极管可靠性。公开并要求保护其他实施例。
