  • Abstract
    We have developed a wideband semiconductor optical amplifier as a gain chip for a C - and L -band external cavity tunable laser. We introduced a coupled quantum well structure to obtain gain spectrum covering both bands. Low threshold current deviation, over 13-dBm fiber coupled power, and high sidemode suppression ratio were demonstrated across a 77-nm tuning range.
