The design is based on a 320nm-thick butt jointed passive waveguide optimized for carrier injection tuning. The butt-joint technology enable optimize the passive waveguide as well as active section. By tuning mirror sections,the laser provides 35nm tuning while maintaining 〉30dB sidemode suppression ratio.展开更多
