The effect of length on the yield of second-order distributed feedback lasers with cleaved facets capable of operating in a single longitudinal mode and on their characteristics has been studied experimentally. The optimum length of 200 ..mu..m was determined in reference to the coupling coefficient and the end-facet reflectivity. A yield of more than 70% was obtained for lasers 200 ..mu..m in length capable of operating at a level of at least 10 mW and over.
