Abstract

The effect of the various number of p-DBR pairs on output performance of GaAs MQWs VCSEL is numerically investigated using ISETCAD simulation program. Relevant VCSEL design with numerous (DBR) pairs has been designed and characterized. It was observed that the number of quarter-wave DBR remaining in the upper mirror can be chosen to achieve optimum performance for the VCSEL in a top surface emitting geometry, such as maximum output power, threshold current, slope output efficiency and differential quantum efficiency and mode gain.
