Remote Sensing Puts Focus on Climate Change
As temperatures and carbon dioxide concentrations rise to levels not previously recorded, shifts in weather and other environmental changes are impacting the global landscape. With the U.N. recording one climate-related crisis every week in 2019, such as the forest fires in the U.S. and bushfires in Australia, the consequences of such a globally disrupted climate are many and difficult to track. This is so because of variables such as altitude, movement, and the size of equipment used to measure these phenomena.

Pandemic Delays Sessions, Drives Conferences Online
During a time of year when many representatives of the photonics industry would be gathering at conferences in Europe and beyond, the COVID-19 pandemic has necessitated a shift in the timing and format of trade shows. Some are being postponed, others are being presented virtually, and others have been outright canceled. Select events may be expected to take place as planned, while conference committees monitor the situation carefully.

CEA-Leti has set a new world record for throughput in light communications (VLC). The researchers used a single 10-μm GaN blue micro-LED to achieve a data transmission rate of 7.7 Gb/s, compared to the previous record of 5.1 Gb/s. The transmission rate marks another step toward commercialization and use of VLC.
