Abstract
A rigorous approach is presented for evaluation of reflection/transmission at the end-facets of distributed feedback (DFB) lasers. The calculations are based on a rigorous two-dimensional model to find the field distribution inside the periodic region. Moreover, it utilizes an efficient mode-matching procedure which is discussed in the paper. Although the end-facet effects in DFB lasers can rigorously be taken into account by using this approach, the computational efficiency can also be maintained quite high.
