Abstract:This paper presents the characteristics of C+L band semiconductor optical amplifier based multi-wavelength laser with the variation of output optical coupling ratios. The configuration was tested with different coupling ratios from 10% to 90%. Meanwhile, the semiconductor optical amplifier injection currents varied from 110 mA to 340 mA in a step of 10 mA. The optimum coupling ratios were observed at 30%, 40%, 50% and 60% since it produces the maximum number of lasing lines, optical signal-to-noise ratio and a… Show more
