Finite element analysis of surface modes in phononic crystal waveguides

The study of surface modes in phononic crystal waveguides in the hypersonic regime is a burgeoning field with a large number of possible applications. By using the finite element method, the band structure and the corresponding transmission spectrum of surface acoustic waves in phononic crystal waveguides generated by line defects in a silicon pillar-substrate system were calculated and investi...

Finite Element Analysis of Open - type Dielectric / Optical Waveguides

Optical fibers or integrated optical waveguides have arbitrary cross-sectional index or refraction distribution. An efficient finite element method for analyzing the propagation characteristics of dielectric / optical waveguides with open boundary is presented. The propagation modes are hybrid, for which a variational expression is formulated in terms of the longitudinal electric and magnetic f...

Modeling of optical aberration correction using a liquid crystal device

* [email protected], Tel: (330) 672-2511 ABSTRACT Gruneisen , has shown that small, light weight, liquid crystal based devices can correct for the optical distortion caused by an imperfect primary mirror in a telescope and has discussed the efficiency of this correction. In this paper we expand on that work and propose a semianalytical approach for quantifying the efficiency of a liquid crystal bas...

Time-Domain Finite Element Modeling of 3D Integrated Optical Devices

Introduction As integrated optical devices become more sophisticated, so does the experimentation and analysis required to design them. By augmenting conventional experiments with rigorous computer modeling we can lower costs, shorten schedules, and provide faster, more accurate predictions. Discrete modeling codes using finite differences or finite elements are the most general, albeit expensi...
