Abstract
The interaction of a mesoscopic Josephson junction with the second-order ex citation of the even coherent state is investigated. It is found that the e xpectation value and the fluctuation of supercurrent can exhibit de compone nts. The static supercurrent flows in the positive or negative direction, w hich depends on the phase of the light field. It is shown that the de compo nents of the supercurrent fluctuation are also related to the phase of the light field.
