The second-order spatial subwavelength interference pattern is observed in a modified Michelson interferometer with single-mode continuous-wave laser beams. By analyzing our subwavelength interference experiment based on Feynman’s path integral theory, a unified interpretation for all the second-order subwavelength interference is suggested.
