NRL Improves Optical Efficiency in Nanophotonic Devices

A team of physicists, headed by the U.S. Naval Research Laboratory (NRL), have demonstrated the means to improve the optical loss characteristics and transmission efficiency of hexagonal boron nitride devices, enabling very small lasers and nanoscale optics. “The applications for this research are considerably broad,” said Dr. Alexander J. Giles, research physicist, NRL Electronics Science

Navy Pairs Thermal Imaging with Spectroscopy for Standoff Chemical Detection

Detecting trace quantities of explosives, chemical or biological agents on a variety of surfaces is challenging—especially from a distance without physically collecting a sample. Spectroscopic techniques have been used, but even though they can be highly selective, they have poor sensitivity. Researchers are increasingly using thermal infrared imaging techniques because they can be safely used
