Abstract :
A new type of vertical-cavity surface-emitting laser (VCSEL) is proposed and analyzed to show the possibility of optical pumping from an integrated edge-emitting laser. With this scheme, it may be possible to make VCSEL´s of very small dimensions and VCSEL arrays. The laser design utilizes dopant induced intermixing of quantum wells (QW´s) to provide different gain regions for the surface and edge-emitting sections. The multimode rate equations are used to evaluate the possibility of such a laser and the roles of the various design parameters are discussed. It is seen that efficient surface photon emission is possible for high vertical-cavity mirror reflectivities and sufficient separation of bandgap energies for the two QW gain regions
