    • PURPOSE: A polarization-insensitive(PI) semiconductor optical amplifier(SOA) is provided to control amplification regarding each mode and to approximately make the amplification regarding each mode coincide with each other, by controlling strain regarding respective regions of each mode to fall within a predetermined scope, and by applying current controlled through each electrode allotted to each region. CONSTITUTION: An optical amplifier has a crystal growth layer of a multilayered structure including an active layer(30) formed on a substrate(60). The active layer includes the first and second region having different polarization modes. An electrode unit(71,72) independently applies current to the respective regions of the active layer.
    • 目的:提供偏振不敏感(PI)半导体光放大器(SOA)以控制关于每个模式的放大,并且通过将每种模式的各个区域的应变控制在一个 并且通过施加电流控制通过分配给每个区域的每个电极。 构成:光放大器具有包括在基板(60)上形成的有源层(30)的多层结构的晶体生长层。 有源层包括具有不同偏振模式的第一和第二区域。 电极单元(71,72)独立地将电流施加到有源层的各个区域。
