Abstract
The performance of 850 nm GaAs multiple quantum well (MQWs) vertical cavity surface emitting laser (VCSEL) laser
structure has been numerically investigated by using laser technology-integrated program ISETCAD simulation. The effect
of the doping concentration on the VCSEL output performance has been investigated. The maximum output power and
lower threshold current was observed when both distributed Bragg reflector DBR and spacer layers are doped with high
level doping concentration. In addition, it was observed that doping can strongly affect the slope efficiency of the VCSEL.
