1.82 \mu m distributed feedback lasers with InGaAs/InGaAsP multiple quantum well

High-strained InGaAs/InGaAsP multiple quantum wells (MQWs) distributed feedback (DFB) lasers, fabricated using metal organic chemical vapor deposition, are presented at 1.82 \mu m with a high side-mode-suppression ratio of 49.53 dB. The current- and temperature-tuning rates of the DFB mode wavelengt
