Abstract :
This paper presents a simulation analysis of distributed Bragg reflectors (DBRs) and their affect on the characteristics of vertical-cavity surface-emitting lasers (VCSELs). The SimWindows semiconductor device simulator models the close interaction between electrical, optical, and thermal processes present in VCSELs. This simulator is used to examine the electrical characteristics of some simple DBR designs. Due to the different transport characteristics of electrons and holes, these results will show that n-type DBR designs must be different than p-type designs in order to achieve the best operating characteristics for the overall laser. This analysis will demonstrate the improvement in the characteristics by comparing the simulation results of a standard VCSEL with the results of a VCSEL using improved DBR designs
