[Abstract]:Based on waveguide theory and equivalent refractive index method, asymmetric waveguide isolated double-channel ridge edge-emitting lasers are designed and fabricated. Finally, a low min single base side mode 852 nm laser is obtained. The influence of the aspect ratio parameter design of different ridges on the lateral mode characteristics of the laser is studied in detail, and the stable output of the single base side mode of the ridged waveguide side emitting laser is realized without coating on the cavity surface. At the same time, the lasing wavelength can be accurately tuned to 852 nm;. The working current is up to 150 mA, the working temperature is 30 鈩，
