The concept of a Microstructured Optical Fiber-based Surface Plasmon Resonance sensor with optimized microfluidics is proposed. In such a sensor plasmons on the inner surface of large metallized channels containing analyte can be excited by a fundamental mode of a single mode microstructured fiber. Phase matching between plasmon and a core mode can be enforced by introducing air filled microstr...

The leakage loss due to TM-TE mode coupling of TM-like whispering gallery mode in silicon-on-insulator (SOI) thin-ridge disk resonators is investigated for the first time to the best of our knowledge. We show that the propagation losses of TM-like mode in thin-ridge SOI disk resonators are significantly impacted by the radius of the disk. This behavior is predicted by a simple phenomenological ...

One configuration for realizing voltage-mode multifunction filters and another configuration for realizing current-mode multifunction filters using current feedback amplifiers (CFAs) are presented. The proposed voltage-mode circuit exhibit simultaneously lowpass and bandpass filters. The proposed current-mode circuit exhibit simultaneously lowpass, bandpass and highpass filters. The proposed ci...

A novel robust active appearance model (AAM) matching algorithm is presented. The method consists of two main stages. First, initial residuals are clustered by a non parametric mean shift mode detection step. Second, modes without gross outliers are selected using an objective function. Robustness of the matching procedure is demonstrated on a variety of examples with different noise conditions...

This paper presents an overview of substrate integrated waveguide (SIW) design activities at the University of Victoria. Mode-matching techniques (MMTs) are employed to facilitate the design of planar SIW circuits as well as surface mounted waveguide (SMW) components. Active component integration and antenna design employ commercially available field solvers. Each category is highlighted by a s...

A high-efficiency silicon strip waveguide to plasmonic slot waveguide converter based on the hybrid silicon-gold taper is proposed and optimized. Through investigating the mode matching, the effective index matching, and the metallic absorption loss considerations, the hybrid silicon-gold taper with an overall length of 1.7 μm having a very high conversion efficiency of 93.3% at 1550nm is achie...

A method for increasing the coupling efficiency between ridge optical waveguides and PhCCRWs is described. This increase is achieved via W1 channel waveguide sections, formed within a two-dimensional triangular lattice photonic crystal using mode-matching. The mode-matching is achieved by low quality-factor modified cavities added to both the input and output ports of the PhCCRW. A three dimens...

The current asphalt pavement design theory is a traditional line elastic theory. voltage resistance recovery modulus used as the material stiffness parameter in design, which does not fully consider significant differences between road pull-up modulus. Therefore, to improve overall stress of structure, this article started from perspective volume structure layer, analyzed development characteri...
