Guided mode biosensor based on grating coupled porous silicon waveguide.
Porous silicon waveguide biosensors that utilize grating couplers etched directly into porous silicon are demonstrated for improved molecular detection capabilities. Molecules are infiltrated through the grating couplers into the waveguide where they can interact with a guided waveguide mode. Hybridization of nucleic acids inside the waveguide is shown to significantly perturb the wave vector o...
متن کاملRadiatively coupled waveguide polarization splitter simulated by wave-matching based coupled mode theory
Abstract: Coupled mode theory is applied to an arrangement of three raised strip waveguides with a multimode central strip. We use semivectorial numerically computed modes of the three single isolated waveguides as a basis for a propagating supermode analysis of the entire structure. The pronounced polarization dependence of the raised strip guides allows for the design of a conveniently short ...
متن کاملDesign and Modeling of Waveguide-Coupled Single-Mode Microring Resonators
We discuss a first-order design tool for waveguidecoupled microring resonators based on an approximate solution of the wave propagation in a microring waveguide with micronsize radius of curvature and a large lateral index contrast. The model makes use of the conformal transformation method and a linear approximation of the refractive index profile, and takes into account the effect of waveguid...
متن کاملCoupled mode theory for photonic crystal cavity-waveguide interaction.
We derive a coupled mode theory for the interaction of an optical cavity with a waveguide that includes waveguide dispersion. The theory can be applied to photonic crystal cavity waveguide structures. We derive an analytical solution to the add and drop spectra arising from such interactions in the limit of linear dispersion. In this limit, the spectra can accurately predict the cold cavity qua...
متن کاملSize Effect in Waveguide Coupled Whispering Gallery Mode Disk Resonators
We investigate the bound and evanescent fields of the optical whispering gallery modes which are supported by a toroid microcavity and which may be used for a wide range of applications. Results of simulations using finite-difference time domain solutions of Maxwell’s equations are compared with semi-analytical solutions based on coupled mode theory. Key parameters such as resonance frequencies...
