Paper Abstract

We propose a new scheme of lasing in a nano-grating with Fano resonance by the independent control of dark and bright modes. The controllability of both dark and bright modes can be achieved by fine-tuning the widths of two kinds of metallic stripes in the nano-grating. It enables the match between resonant frequencies of the nano-grating structure and the absorption and emission frequencies of gain medium. For example, changing the width of the thin strip is to hit the emission peak of the gain medium, while the fat strip corresponds to the absorption peak of the gain medium. We work out an optimal example of silver grating immersing Rhodamine dye, verifying the lasing dynamic process with minimum threshold and maximum output power. It may provide a new way on low-threshold and high-efficient plasmon laser.
