Abstract :
The spectral linewidth of AlGaAs/GaAs distributed feedback (DFB) lasers was measured for the first time. The linewidth-power product decreased with temperature, which indicates that the relative position of the oscillation wavelength and the gain peak strongly affects the linewidth of DFB lasers.
