The properties of the 808nm GaInAsP/GaInP quantum well structure lasers with asymmetric waveguide are numerically studied with a commercial LASTIP simulation program. The simulation results show that the laser performance of the 808nm GaInAsP/GaInP quantum well structure with asymmetric waveguide has a lower threshold current and higher slope efficiency, lower series resistance than symmetric waveguide...
The coupling application of tapered optical fiber and semiconductor laser has great practical value. The beam shaping effect of the tapered area is analyzed based on the principle of geometrical optics. The coupling model of the semiconductor laser and the tapered fiber is built with ZEMAX. The influence of the coupling efficiency caused by the different working distance between the source and the...
The selection of semiconductor laser package materials including heat sink and solder has an important impact to the cooling and life of the laser, and thus performing related studies is very important. A C-Mount package semiconductor laser model was established in this paper, and thermal characteristic of different kinds of heat sink materials was simulated by the finite element software ANSYS. The...
