Abstract

The influence of end reflectivity on the excess noise factor in distributed feedback lasers is analyzed. It is shown that the end reflectivity affects the excess-noise factor markedly in the weak and moderate coupling region. In particular, in this coupling region the noise level in the laser structure strongly depends on the end reflectivity phase. Moreover, in the weak and moderate coupling region, the excess-noise factor decreases with an increasing end reflectivity amplitude; in the strong coupling region the opposite behavior is observed
