    摘要： According to one aspect, the invention relates to an optical safety component having a plasmonic effect intended to be observed by transmission, including two layers (101, 103) made of a transparent dielectric material, a metal layer (102) that is arranged between said layers made of dielectric material to form two dielectric-metal interfaces (105, 106), and is structured to form on at least a portion thereof corrugations (104) that are capable of coupling surface plasmon modes supported by said dielectric-metal interfaces with an incident light wave. The corrugations are arranged in a first coupling area in a first main direction and in at least one second coupling area separate from said first coupling area, in a second main direction that is substantially perpendicular to said first main direction, said metal layer being continuous on each one of said coupling areas.
