An optically pumped surface-normal optical amplifier with a 100-period InGaAs/InGaAlAs multiple quantum well is fabricated, and a signal gain exceeding 2 dB is observed for what we believe to be the first time. A laser diode with the wavelength λ of 1.45 μm is used for pumping. An optical single-pass gain as high as 2.4 dB is obtained at λ = 1.585 μm with 65-mW pumping (spot diameter 12 μm). |
