In the work we consider two new routes to impose control on the optical waveguides propagation. The first approach is based on the Kerr effect caused by the THz field, which strength is manifold times enhanced by the presence of a nanoslit in a metallic film surrounding the waveguide. The second approach utilizes the gain-core effect on plasmonics modes in metal-semiconductor-metal structures. Our simulations prove that it is quite reasonable to realize both control schemes experimentally.
