Abstract :
An analytical approximation is found for 
, the TE0 radiation confinement factor in symmetric heterostructures, by using a combination of its asymptotes in the limits of very thin active layers and thick active layers, respectively. The exact expression for is calculated and compared to the approximation formula. It is found that for any light guiding planar double heterostructure (DH) configuration the approximation is at most -1.5 percent off with respect to the exact value.
