This paper describes the development of aluminum nitride (AlN) resonant accelerometers that can be integrated directly over foundry CMOS circuitry. Acceleration is measured by a change in resonant frequency of AlN double-ended tuning-fork (DETF) reso

Microfabricated acoustic crystals have been designed and experimentally verified. The acoustic crystals are realized by including tungsten (W) scatterers in a SiO2 matrix. Wide frequency ranges where acoustic waves are forbidden to exist (acoustic ba

Theoretical models have been developed to investigate the reflection and transmission spectra, and photonic band structure for a midinfrared layer-by-layer metallic photonic crystal. It is found that photonic band gap effects due to global coupling b

The emission and detection of electromagnetic radiation are essential optical processes that govern performance of lasers, detectors and solar cells. Through light-photonic crystal interaction, a three-dimensional (3D) photonic crystal offers a way t

The localization of light to less than a cubic wavelength, ${\ensuremath{\lambda}}^{3},$ in all three dimensions has important quantum consequences. A defect formed inside a three-dimensional (3D) photonic crystal provides a unique optical environmen

The authors have used chemical vapor deposition to grow ternary tungsten-based diffusion barriers to determine if they exhibit properties similar to those of sputter-deposited ternaries. A range of different W-B-N compositions in a band of compositio

A three-dimensional tungsten photonic crystal is realized with a photonic band edge at λ∼4 μm wavelength. Its thermal emission is suppressed in the band gap regime and, at the same time, exhibits sharp peaks near the band edge. It is further obse

Phononic crystals (or acoustic crystals) are the acoustic wave analogue of photonic crystals. Here a periodic array of scattering inclusions located in a homogeneous host material forbids certain ranges of acoustic frequencies from existence within t

We present ultrafast all-optical switching measurements of Si woodpile photonic band gap crystals. The crystals are spatially homogeneously excited and probed by measuring reflectivity over an octave in frequency (including the telecommunication rang
