Electronically Dimmable Aircraft Windows

That was the challenge posed to Gentex by Boeing. Window shades typically do the job on an airplane, but they’re cumbersome to operate, expensive to maintain, and do little to reflect the hightech nature of today’s modern aircraft. They’re an analog technology holdover operating in the digital age.

Hydrodynamic Drag Force Measurement of a Functionalized Surface Exhibiting Superhydrophobic Properties

With superhydrophobic properties being extended to a variety of metallic substrates through the process of ablation due to femto-second laser surface processing (FLSP), it is important to understand the hydrodynamic benefits of such a material, as well as its resiliency. This research focuses on the skin friction drag effects of a superhydrophobic flat plate compared to an untreated flat plate of the same material and geometry. The resiliency of this material will also be tested through the use of an accelerated corrosion fog chamber using both treated and untreated aluminum samples.

High-Power Broadband Multispectral Source on a Hybrid Silicon Chip

For applications in manufacturing, remote sensing, medicine, military, and fundamental science, an ideal laser would have high output power and a diffraction-limited beam. The figure-of-merit to describe this property is the brightness, which scales proportional to output power and inverse to the beam quality factor M2.

Stimulated Brillouin Scattering (SBS) Suppression and Long Delivery Fibers at the Multikilowatt Level with Chirped Seed Lasers

One obstacle in the scaling of high-power fiber lasers arises because of nonlinear effects (e.g., stimulated Brillouin scattering [SBS]) due to the large intensity times length product. Efforts to raise the power threshold include:

Erbium Doped GaN Lasers by Optical Pumping

The main objective of this research was to construct an optical pump system that would allow the study of Er:GaN materials under 980 nm resonant excitation to be carried out. The results obtained from the optically pumped studies could then be utilized to guide crystal growth and laser design.
