文摘

The transport property for the four level coupling system is accurately solved. A scheme to obtain reflective spectrum with tunable ultranarrow band is proposed. The spectrum width can be narrowed avoiding the impact of the loss. The position of the peak can be tunable by choosing the appropriate parameters.
