“…Consequently, they have become one of the research hot-spots of laser technology. Paschke and Sumpf et al [4] have found that using different electrodes to separately drive the master area and amplify area can obtain high power and nearly diffraction limited output laser. Since a DBR laser with first order gratings emits two degenerate modes, there are lobes in the far field.…”

We use traveling wave coupling theory to investigate the time domain characteristics of tapered semiconductor lasers with DBR gratings. We analyze the influence of the length of second order gratings on the power and spectrum of output light, and optimizing the length of gratings, in order to reduce the mode competition effect in the device, and obtain the high power output light wave with good longitudinal mode characteristics.
