LASERS NEWS
AFRL, Industry Partner Place Hybrid Silicon Lasers in the Crosshairs WRIGHT-PATTERSON A.F.B., Ohio, April 15, 2021 — The Air Force Research Laboratory (AFRL) approved a Cooperative Research and Development Agreement with the Nanoelectronics Materials Branch and Iris Light Technologies that will focus on the development of hybrid silicon lasers. Success in getting silicon chips to emit significant amount of light has been recent, but limited. A process that alloys silicon with germanium advanced the technology, though the process is tedious and expensive. Dr. Chad Husko, CEO and founder of Iris
NIST’s Agricomb Measures Gas Emissions from Cows GAITHERSBURG, Md., April 14, 2021 — The “agricomb,” an optical frequency comb developed by researchers from the National Institute of Standards and Technology (NIST), is able to measure gas emissions from cow eructation and flatulence. The device may as a result aid in the...
Tissue-Integrated Microlasers Measure Beating Heart of Zebra Fish ST.
