Analysis of characteristics with Airy surface plasmon in SPPs lasing

In order to study on surface plasmon polaritons (SPPs) which have Airy plasma characteristics, the special nature of Airy plasma was analyzed and simulated. Based on the principle of SPPs lasing, the theoretical of Airy plasma eigenstates was analyzed. The nature of Airy plasma on the grating structures of SPPs lasing was studied. The results indicates that the Airy surface plasmon not only have characteristics with amplification in near field energy zoom and fast spread, but also can control spread using its characteristics; Airy surface plasmon can control energy loss only in rang width, which cannot appear Airy surface plasmon when its width is less than 600 nm; lasing energy of different width have same trend; Airy surface plasmon can achieve fast spread in the condition of low excitation energy, it has not obvious effect when increase lasing energy after 2.3 eV. There is a positive significance for studying strong localization of SPPs, surface optical processing with SP and linear control SP of no diffraction.
