Abstract

At present the laser diodes used in optical fiber communications systems are based on GaInPAs. These lasers have a bad thermal performance and promising substitutes are GaInNAs lasers. In this paper a study of influence of the ridge height on the temperature distribution in GaInNAs laser diodes is presented. To find the temperature distribution the heat conduction equation was solved using the Finite Difference Method and a two-dimensional model of heat flow. The simulation was performed in Mathematica 7.0 varying: the length of the diode, the amount of wells in the active zone and the height of the ridge contact. The thermal resistance (Rt) of the devices was calculated and compared with experimental results reported by other authors, obtaining good agreement.Our results suggest the potential of GaInNAs lasers.
