Abstract: In this paper we present significant study on the effect of temperature on the characteristics of a diode laser system subjected to external optical feedback. The presence of the feedback is seen to reduce the threshold current and slope efficiency which are important parameters for the solitary diode laser. In this sense the threshold reduction is a good indicator of the feedback level. At certain temperatures, the effect of optical feedback was actually seen to cause slight increase on the threshold current value. The results presented in this paper with regard to the temperature dependence and single optical feedback effect on the threshold and optical power output of diode laser systems will help in understanding the dynamical behavior of such systems.
