Resumo
Spontaneous emission in a vertical cavity surface emitting laser (VCSEL) have been studied. It was estimated that a significant part of the spontaneous emission (~1/3) in a conventional VCSEL goes into a waveguide mode that propagates in the plane of the Bragg mirrors. The theoretical study of a recently proposed anti-waveguide VCSEL design is presented and the damping of the waveguide mode emission is shown. Moreover we calculate that 3λ/2-cavity AVCSEL has almost the same gain value for vertical mode as conventional λ-VCSEL despite the higher cavity width due to the light redistribution effect while λ/2-cavity AVCSEL has 19% higher gain.
