We developed a method to fabricate a periodic array of three-dimensional crescent-like holes (3DCLH) via an inverted hemispherical colloidal lithography. It is found that there exists an extraordinary optical transmission (EOT) in this non-planar perforated periodic array of 3DCLH which is caused by an asymmetric localized surface plasmon resonance. It is also found that the EOT peak is consistent with the change of incident angles. This structure might be useful for the optical sensing and optical integrated circuits.
