Photo-induced voltage due to photon drag effect is investigated for metallic photonic crystal slabs (PCS) with symmetric and asymmetric unit cells. In the symmetric structure, the signal is antisymmetric as a function of the incident angle, while in the asymmetric structure it is asymmetric. When the laser beam is normally incident to the sample, the photovoltage is observed only for PCS with asymmetric unit cells and its laser wavelength dependence is readily described in terms of uneven diffraction. The phenomenon can be referred to as optical rectification due to photonic scale asymmetry.
