| Abstract(in English) | Semiconductor optical amplifier has advantages of small size and low cost. In practice it seems to be important to make the devices which have the same characteristics with each other. We propose ridge waveguide with reverse mesa side-walls because this type needs very simple process to make it. We used TiO_2/SiO_2 double layer anti-reflection coat by Electron-Beam sputtering method which has wide tolerance of making error. We can easily attain <0.2% reflectivity and suppress lasing. The amplifier shows the same characteristics as buried usual one with complicated process : single path gain is 19dB and saturation output power is +5dBm at 200mA. |
