Notes:
Using tensile-strained InGaAs/InGaAsP multiple quantum well material to increase the gain bandwidth, we demonstrate a tuning range of 74.4 nm with sidemode-suppression ratio of (approximately-greater-than)25 dB and as high as 34 dB in a broadly tunable vertical-coupler filtered laser at 1.55 μm. Due to its wide gain bandwidth and significant gain-peak shift to shorter wavelengths with gain current increase, the tensile-strained quantum well material is well suited for broadly tunable lasers.
