By fabricating an ultra‐small defect aperture in a subwavelength plasmonic waveguide experimentally, the surface‐plasmon‐polariton (SPP) mode guided by the plasmonic waveguide was directionally coupled from both of the p‐ and s‐polarized incident beams in a broad bandwidth. This completely overcame the polarization dependence of the SPP coupling from the free‐space light. Such a polarization‐free SPP coupler is of importance in circuits for fully‐optical processing of information with a deep‐subwavelength footprint.
