OSA Statement on the Coronavirus Aid, Relief and Economic Security (CARES) Act
With the impact of COVID-19 (Coronavirus) disrupting important scientific research that could lead to new discoveries and technologies to combat the pandemic, the Coronavirus Aid, Relief and Economic Security (CARES) Act approved by the U.S. Congress provides critical resources to the optics and photonics community. Across the globe, researchers are racing to develop vaccines and therapeutics to contain the spread of the virus. This infusion of U.S. government funds to science agencies and research institutions will accelerate studies and testing capabilities, increasing our knowledge of the disease and improving treatment options.

New Fabrication Approach Paves Way to Low Cost Mid-Infrared Lasers Useful for Sensing
For the first time, researchers have fabricated high-performance mid-infrared laser diodes directly on microelectronics-compatible silicon substrates. The new lasers could enable the widespread development of low-cost sensors for real-time, accurate environmental sensing for applications such as air pollution monitoring, food safety analysis, and detecting leaks in pipes.

Precision Mirrors Poised to Improve Sensitivity of Gravitational Wave Detectors
Deformable mirrors, which are used to shape and control laser light, have a surface made of tiny mirrors that can each be moved, or actuated, to change the overall shape of the mirror. As detailed in The Optical Society’s (OSA) journal Applied Optics, Cao and colleagues have, for the first time, made a deformable mirror based on the bimetallic effect in which a temperature change is used to achieve mechanical displacement.

Long-Distance Fiber Link Poised to Create Powerful Networks of Optical Clocks
An academic-industrial team in Japan has connected three laboratories in a 100-kilometer region with an optical telecommunications fiber network stable enough to remotely interrogate optical atomic clocks. This type of fiber link is poised to expand the use of these extremely precise timekeepers by creating an infrastructure that could be used in a wide range of applications such as communication and navigation systems.
