Abstract
This chapter discusses, in a tutorial way, the basic theory of electromagnetic emission by a dipole in a planar cavity, which is representative for the spontaneous emission in micro-cavity LED’s. We start from the expansion of a point source field into plane waves. Then the enhancement and inhibition effects of a cavity upon plane wave components are introduced. Next. the vectorial aspects af dealing with a dipole field are discussed, as well as the effects caused by the use of realistic mirrors. Finally we describe the effect of the cavity upon the carrier lifetime and give a discussion of guided modes. More in particular the plane wave decomposition and normal mode decomposition are confronted with each other.
