Abstract：To obtain a stable amplified spontaneous emission (ASE) source for complex environment applications, we design an ASE source and study the output power and spectral characteristics under different ambient temperatures. We optimize the structure of the ASE source to flatten the ASE spectrum, and study the output characteristics in terms of output power and optical spectrum under different pump powers. Then the performance of the ASE source is investigated in the temperature range from $-$18.9$^{\circ\!}$C to 50$^{\circ\!}$C. A stable-power and flat-spectrum ASE source can be obtained by structural optimization and pump control.
