Abstract: | We proposed a three-layer waveguide as an optical sensor for homogeneous sensing applications. A guiding layer of the proposed
structure is considered as lossy left-handed material (LHM) with simultaneously the complex negative electric permittivity
ɛ and the complex negative magnetic permeability μ. We also assume a cladding layer to have an intensity-dependent refractive
index. Sensitivity of the proposed optical waveguide sensor is derived and its dependence on different parameters of a waveguide
is studied. |
