Abstract(in Japanese) (See Japanese page)
Abstract(in English) A semiconductor optical amplifier (SOA) using highly stacked InAs quantum dots (QDs) as a gain media were fabricated. 20 InAs QD layers were successfully stacked without any degradation of crystal quality by strain compensation technique. A wide range 1.55μm band gain was observed in this SOA module. The maximum gain reached to 25 dB at 1520 nm with the input power below-40dBm.
