Abstract

An analytical approximation is found for $\\Gamma _{0}$ , the TE0radiation 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 $\\Gamma _{0}$ 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 $\\Gamma _{0}$ value.
