C+L BAND SOA MULTI-WAVELENGTH LASER WITH THE VARIATION OF OPTICAL COUPLING RATIOS

This paper presents the characteristics of C+L band semiconductor optical amplifier based multi-wavelength laser with variation output coupling ratios. The configuration was tested different ratios from 10% to 90%. Meanwhile, injection currents varied 110 mA 340 in a step 10 mA. optimum were observed at 30%, 40%, 50% and 60% since it produces maximum number lasing lines, signal-to-noise ratio average peak power. These also correspond minimum drive current that initiates first lines. At 280 mA, has capability generate up 42 dominant lines power -21 dBm -35 an 9 dB 11 dB. Furthermore, required initiate ratio. can effectively practically act as source, especially sensing communication.
