Abstract

The superiority of gain or loss-coupled DFB lasers over the index coupled ones are evident in many respects. However the fabrication of first order gain or loss coupled gratings involves many difficulties. Therefore we are practically restricted to employing higher order gain or loss-coupled gratings. One of the main disadvantages of higher order gratings is radiation losses. To take into account both the effects of higher order modes on coupling and losses in linear regime, we apply a well-known coupled wave analysis due to Striefer et al. In 1977 to loss coupled DFB lasers. This theory using the first order perturbation analysis is suitable for analyzing shallow gratings. It leads to a pair of coupled wave equations, where coefficients indicate all the possible coupling losses.
