Abstract

A comprehensive design for high‐power DFB lasers is discussed. An anti‐reflection/high‐reflection facet structure and optimized coupling between forward and backward propagation waves in continuous corrugation‐type devices are shown in to be essential for this purpose. By applying the forementioned optimization to 1.5 μm DFB laser parameters, a maximum output power of 45 mW and a quantum efficiency of 37 percent are obtained at 20°C. The devices oscillate in a single‐longitudinal‐mode with a side‐mode suppression ratio of more than 30 dB under 1 GHz sinusoidal modulation.
