| Summary: | Sensitivity of optical parameters is a significant topic in developing optoelectronic devices. The stress sensitivity of nonlinear optical waveguides is closely related to hydrostatic stress. The hydrostatic stress can cause anisotropic and inhomogeneous distribution of the refractive index. In this paper analytical and numerical calculations are performed to study the effect of hydrostatic stress on the sensitivity of nonlinear optical waveguide sensors. The optical performance of the waveguide sensors under various hydrostatic stress states is also investigated. Transverse magnetic modes (TM) are considered in addition to transverse electric modes (TE) to study anisotropy. It is found that the value of the hydrostatic stress can change the value of the cutoff thickness. These changes may induce multimode. Moreover, the hydrostatic stresses influence the values of the stress sensitivity of the waveguide sensors and present anisotropic behavior to the system. |
