L. Borruel scite author profile

The basic operating principles of gain guided tapered lasers are studied in detail by means of numerical simulations. The carrier induced lensing effect caused by spatial hole burning is described as the main mechanism limiting the device performance. The influence of the following design parameters in the maximum output power and beam brightness is analyzed: refractive index step of the ridge waveguide section, angle and length of the tapered section, and the use of beam spoilers. The results provide design guidelines for improving the device performance.
