title = "150-nm continuous tuning of external-cavity quantum-dot lasers operated below 90 mA",
abstract = "Low threshold and widely tunable InAs/InGaAs/GaAs quantum-dot external-cavity lasers are implemented with gratingcoupled Littrow configuration. Throughout the tuning range of 130 nm, from 1160 to 1290 nm, the threshold current density is less than 0.9 kA/cm2 and without noticeable threshold jump. For a shorter-cavity device, the injection current is kept at a record low value of 90 mA but the tuning range is further extended from 1143 to 1293 nm. We discuss the effect of cavity length on the tuning characteristics and propose the strategy for design and optimization of multilayer quantum-dot structure.",
