An optically defined phononic crystal defect

Autor: Clark, Thomas J., Bernard, Simon, Ma, Jiaxing, Dumont, Vincent, Sankey, Jack C.

We demonstrate a mechanical crystal with an optically programmable defect mode. By applying an optical spring to a single unit cell of a phononic crystal membrane, we smoothly transfer a single mechanical mode into the bandgap, thereby localizing its

Monitored wet-etch removal of individual dielectric layers from high-finesse Bragg mirrors

Autor: Bernard, Simon, Clark, Thomas J., Dumont, Vincent, Ma, Jiaxing, Sankey, Jack C.

It is prohibitively expensive to deposit customized dielectric coatings on individual optics. One solution is to batch-coat many optics with extra dielectric layers, then remove layers from individual optics as needed. Here we present a low-cost, sin

Backward Uniqueness for a PDE Fluid-Structure Interaction

Autor: Avalos, George, Clark, Thomas J.

In this work, we establish the so-called backward uniqiueness property for a coupled system of partial differential equations (PDEs) which governs a certain fluid-structure interaction. In particular, a three-dimensional Stokes flow interacts across

A Mixed Variational Formulation for the Wellposedness and Numerical Approximation of a PDE Model Arising in a 3-D Fluid-Structure Interation

Autor: Avalos, George, Clark, Thomas J.

We will present qualitative and numerical results on a partial differential equation (PDE) system which models a certain fluid-structure dynamics. The wellposedness of this PDE model is established by means of constructing for it a nonstandard semigr
