Abstract :
The variations of gain and noise figure with temperature (20-40 degrees C) are investigated for a 1.5 mu m GaInAsP/InP laser amplifier with angled facets. The gain is decreasing by 4-8 dB for a temperature increase of 20 degrees C and the noise figure is increasing by 2-4 dB. For both parameters the variation is smallest on the high wavelength side of the gain peak.
