Optimal control scheme based on the adjoint equation of 1-D heat conduction is developed for transient control of internal temperature profile inside electronic devices such as pulsed laser diode. Joule heating with a thin-film heater is employed as the control input in order to minimize temperature changes of a thin active layer within a modeled laser diode. In numerical simulations, temperature variation of the active layer is successfully suppressed by 70% with heat input prior to the onset of the laser pulse. It is found that the Fourier number of the layer between the control heater and the active layer is the key parameter to minimize the temperature fluctuations.
