High-gain, high-power 1.3 mu m compressive strained MQW optical amplifier

A high-gain and high-saturation output power optical amplifier operating in the 1.3- mu m wavelength region that was fabricated using a compressive-strained multiple-quantum-well active region is described. It is shown that optical gain as high as 27 dB and 3-dB saturation output power as high as 14 dBm were obtained simultaneously.>
