Simple formulae giving the temperature profiles in the stripe-geometry laser diodes with oxide barriers

Simple, approximate formulae describing the temperature distribution in the stripe-geometry laser diode with oxide barriers has been derived in this work. A two-dimensional, heat-spreading model has been used in which the lateral heat spreading as well as the radiative transfer of spontaneous radiation has been taken into account. The resultant formulae have been obtained using the electrical analogue of the heat flow process.
