Abstract :
Inside-cavity diffraction loss resulting from unguided regions and 45 degrees internal total reflection mirror(s) is an important issue for fabricating folded-cavity in-plane surface-emitting lasers. A Fresnel plane-wave decomposition method was applied to analyze this problem. The effective reflectivity of an angle-etched mirror was calculated for deviation of the etched angle and different lengths of the unguided region. The results offer design criteria for fabricating folded-cavity surface-emitting lasers as well as other devices with angle-etched facet(s) for surface normal light coupling.<>
