Abstract :
Operation of a new triple fused long wavelength VCSEL structure is demonstrated for the first time. In this structure both highly resistive p-AlGaAs/GaAs DBR and strained p-GaAs/p-InP fused junction are replaced with a composite mirror comprising a p-InGaAsP/InP partial DBR fused to an undoped AlGaAs/GaAs DBR and an isoperiodic, low barrier p-InP/p-InGaAsP fused junction.
