Abstract
A VCSEL for emitting long wavelength light including a GaAs substrate element, a first mirror stack with mirror pairs in a GaAs/AlGaAs material system lattice matched to a GaInAsN active region with an active structure sandwiched between a first cladding region adjacent the first mirror stack, and a second cladding region. The first and second cladding regions including an InGaP/GaAs material system. The active structure includes a nitride based quantum well and either a GaAsP or a GaAs barrier layer. A second mirror stack is lattice matched to the second cladding region and has mirror pairs in a GaAs/AlGaAs material system.
