Abstract
A tensile-strained InGaAsP/InP multi-quantum-well optical amplifier is constructed which has >or=92 nm bandwidth at 16-dB gain for 50-mA drive current. The wide gain bandwidth is a result of both n=1 and n=2 contributions from the e to 1h transition. These results suggest wide tunability for lasers made from this material.<>
