摘要：
InGaAs/AlGaAs quantum well laterally-coupled distributed feedback (LC-DFB) laser is designed and fabricated by electron beam lithography and reactive ion etching. The LC-DFB laser eliminates the need of a crystal regrowth in a conventional DFB laser fabrication process. A single mode lasing at a wavelength of 967.8 nm with a side mode suppression ratio of 46 dB was achieved under CW operation at room temperature. The threshold current and maximum peak output power were 15 mA and 19 mW at 90 mA injection, respectively.
