Abstract :
This work reports the significant influence of the layout of nonidentical MQWs on the broadband tunability of external-cavity semiconductor lasers. Study shows that, using properly designed MQWs as the laser gain material, the external-cavity semiconductor laser exhibits an extremely broadband tuning range, covering from 1300 nm to 1540 nm. On the other hand, if opposite sequential layout of MQWs is used, tunability covers only from 1290 nm to 1450 nm
