Abstract
Internal thermal stresses in the active layer of a conventional InGaAsP/InP laser may cause polarization instabilities which normally do not exist in conventional AlGaAs/GaAs lasers. We analyze a structure with a buffer layer for Polarization stabilization by compensation of the internal thermal stresses in InGaAsP/InP lasers. Stress analyses are carried out for various structures to obtain the conditions for optimal stress-free structures. The effects of stresses from external sources are also discussed.
