Abstract
Working group I of COST 240 concentrates on the comparison of modelling results and experimental results obtained in different laboratories on DFB lasers. In a first stage, the results of different European laser models obtained for static, dynamic and noise related characteristics have been compared. Several perfectly AR-coated, λ/4-shifted DFB lasers and one DFB laser with cleaved facets have been or are currently being investigated. Here, we will briefly describe some of the results on λ/4-shifted lasers, but more details will be presented at the meeting. From the numerical results obtained so far, it seems that an excellent agreement can be obtained in most cases (the differences between the different results are usually smaller than a typical experimental uncertainty).
