Author Affiliations +
Stress effect on the behavior of optical waveguide sensor consists of dielectric slab inserted between metamaterial (MTM) cladding and substrate is investigated by using numerical calculations. Several MTMs with different values of ε and μ with ε μ = 4 are chosen in order to clarify the variation of stress effect with respect to the material constants. Numerical calculations of the effective index for both transverse electric modes (TE) and transverse magnetic modes (TM) as a function of stress and slab thickness have been performed. It is found that stress affects the performance of the waveguide sensor.
