We demonstrate a scalable photo-thermal process which enables manufacturing of infrared (IR) transmissive glass-ceramic films with gradient refractive index (GRIN) profiles. Spatiallycontrolled laser irradiation creates Pb-rich amorphous phases withi

The development of infrared gradient refractive index (GRIN) components relies on the ability to modify the refractive index and dispersion properties of suitable host materials with a high spatial selectivity and a sufficient magnitude of change. We

BAE Systems has developed an improved tool for exporting optical design coordinates to Computer-Aided Drafting (CAD) software. Existing scripts within common lens design packages export element shapes and rays which is enough for standard systems, bu

Metallic grid layers are used for EMI-shielding and heating on aerospace windows and domes. The authors demonstrate the capability to accurately model the optical transmission, EMI attenuation and diffraction effects of such sub-mm-scale grid structu

Coatings of various metalized patterns are used for heating and electromagnetic interference (EMI) shielding applications. Previous work has focused on macro differences between different types of grids, and has shown good correlation between measure

We have recently demonstrated the ability to measure the absolute change in optical power (focus) of a 152 mm diameter flat mirror in vacuum between room and cryogenic temperatures (133K) with a peak-to-valley measurement error of only 22nm. Such a m

A microring resonator, a circular waveguide adjacent to a straight waveguide, performs selective band-stop filtering for optical telecommunications. Small size and versatility of functionality allow many microrings to be incorporated into a single in

The Levinson-Durbin (LD) algorithm has been used for decades as an alternative to Fast-Fourier Transforms (FFTs) in cases where several cycles of a signal are not available or too expensive to obtain. We describe a new application of this LD algorith
