摘要：
This paper clarifies that the external cavity modes deform optical output response in the DFB lasers by enhancing the relaxation oscillation under NRZ modulation. It is shown that a DFB laser with an asymmetric structure in reflectivity of facets and in position of a lambda/4 phase shift can suppress the influence of the external cavity modes.
