Abstract :
The variation of gain with wavelength of a 1.5 ¿m semiconductor-laser amplifier with antireflection-coated facets has been measured over several modes. The internal gain and resonant wavelength were found using a curve- fitting technique and the dependence of these quantities on bias current and signal power was investigated.
