Finite element stress modeling of InGaAsP/InP lasers

InGaAsP/InP lasers operating at 1.3/spl mu/m and 1.55/spl mu/m wavelength are used currently in many long haul and local loop communication systems. In addition to demands on the performance characteristics of these lasers, their long-term reliability under the operating conditions should also be satisfactory. Strain is one of many factors that can affect laser reliability. The principal objective of the current work is to construct processing related thermal stresses in InP based laser structures.
