Abstract(in English) In this paper, we fabricated the QD-SOA which utilized the 20-layer-stacked quantum dots structure with the strain-compensation technique for the purpose of all optical logic gate device, and measured the fundamental characteristics of the QD-SOA. The device length of fabricated QD-SOA was 1650μm, and when the input light, whose wavelength was 1558 nm, input the QD-SOA, which was driven by 500 mA of injection current, the maximum gain of 20 dB and the modal gain coefficient of 27.9cm^<-1> were obtained. And also, we input femto-second pulse laser light into QD-SOA and observed the auto-correlation waveforms. Compared to the input pulse light, output light from SOA was broadened by 15 %, 55 fs.
