    <title language="eng">Fabrication approach for antiphase narrow linewidth complex coupled 1.55 μm DFB lasers</title>
    <abstract language="eng">A new method for fabricating narrow linewidth antiphase complex coupled MQW DFB lasers by periodically etching the active layer and quartemary InGaAsP overgrowth is reported. The minimum linewidth for a 375 µm long ridge waveguide laser is only 250 kHz at an optical output power of 4 mW.</abstract>
