Ultracompact chip-integrated electromagnetically induced transparency is realized in a single plasmonic composite nanocavity in plasmonic circuits directly. A small lateral dimension of 600 nm is obtained for the composite nanocavity, which is reduced by one order of magnitude compared with previous reports. A large shift of 490 nm in the transparency window center is obtained through covering poly(methyl methacrylate) layer.
