Static and dynamic properties of laterally coupled DFB lasers based on InAs/InP QDash structures
Electronic Letters 41 (2005) 808.

Laterally coupled, complex distributed feedback lasers based on AlInGaAs/InAs/InP quantum dash layers were fabricated by maskless focused ion beam lithography. Continuous-wave powers above 30 mW at room temperature, sidemode suppression ratios of 44 dB and a modulation bandwidth of 7.6 GHz were demonstrated.
