摘要：
We have studied scattering from locally periodic optical potentials. The band-structure characteristics of periodic potentials along with resonances are observed. These features are solely due to the interference from absorptive potentials. Contrary to assertions in the literature, we show that the absorption along with the enhanced reflection induces coherence in quantum systems. We also discuss some conceptual aspects of absorptive potentials.
