Abstract

Semiconductor lasers with good fundamental transverse mode stability have important applications in optical communications, light sources, biomedical and other fields. For Fabry-Perot (FP) lasers, lateral mode control is an important issue. In this paper, the influence of the side double-trench ridge waveguide structure of the semiconductor FP laser on the output mode characteristics is analyzed theoretically. The device is modeled and calculated using matlab software. FP laser with different ridge width and trench width are designed and fabricated using the double-trench ridge waveguide structure. The influence of the leakage loss of the double-trench waveguide structure on the mode output characteristics is analyzed.
