Large lateral shift in a prism-waveguide system with uniaxially anisotropic metamaterial

摘要

We study the lateral shifts of reflected light beams in a prism-waveguide system with uniaxially anisotropic metamaterial including lossless and lossy system. The conditions for appearance of large lateral shift are deduced in a lossless system and the expression of lateral shift in a lossy system is derived. Simulation results illustrate the influence of imaginary part of every parameter in the prism-waveguide system on lateral shift. The anisotropy of metamaterial brings us more flexibility in designing new style photonic devices, such as sensors with high sensitivity based on accurate control of constructive parameters of metamaterial.
