摘要
A suitable structure of narrow linewidth DFB laser is studied experimentally. By thinning the active layer to around 0.07 μm, controlling kL to 1.0, and improving the geometrical uniformity of active region, the linewidth less than 1 MHz is achieved at an output power of around 20 mw in 1.55 μm DFB lasers with 1.2 mm long cavity length.
