Abstract :
DFB lasers have been characterised in terms of linewidth. The effect of antireflection coating on linewidth has been measured. The frequency modulation (FM) response has been measured and the system implications of a nonflat FM behaviour are discussed. Two section DFB lasers with electro-optic tunability are described and results presented.<>
