The present article illustrates the modeling and optimization of a dual-slot waveguide for the application of a refractive index biosensor. The nanometer scale waveguide structure uses the silicon-on-insulator platform for the consideration of higher sensitivity and compactness of a resonator biosensor. The modal analysis is performed using the finite difference method based on full vector eigenmode...
In this work, a detailed performance analysis for a Mach-Zehnder interferometer (MZI) optical switch with a channel profile of titanium-indiffused lithium niobate (Ti:LiNbO3) is presented. The concept of diffusion process controlled modeling has been used to design and optimize its performance. Impacts of Ti-strip thickness on the power imbalance of first 3-dB coupler and crosstalk (CT) levels at...
