Threshold current density and differential quantum efficiency are analyzed for surface emitting (SE) {lambda}/4-shifted distributed feedback (DFB) laser consisting of alternating active and passive layers with a distributed Bragg reflector (DBR). It is shown that the refractive-index periodicity of the active region in DFB structures give rise to unique performances compared to SE DBR lasers with a homogeneous active region.
