We present half vertical cavity surface emitting lasers (VCSELs), based on a new type of InP/AlGaInAs distributed Bragg reflector (DBR) and on InAlAs/AlGaInAs DBR. Lasing effect under pulsed optical pumping in external cavity configuration was obtained. A comparison between these two materials systems is presented, as well as a first step in the design of the active cavity in order to optimize the absorption for the optical pumping.
