FPAs are image sensors that convert infrared light into electrical signals to produce real-time thermal images and are widely used in applications such as surveillance, astronomy and industrial monitoring. Advances in cryogenic FPAs have enabled higher resolution, sensitivity and faster imaging, but they also require data rates exceeding 100 gigabits per second. Conventional electrical interconnects used to support these demands increase heat load through copper connections, which can leak into FPAs, raise noise, and increase cooling requirements and power consumption. https://techxplore.com/news/2026-07-cryogenic-sensors-laser-fast.html Engineering Mon, 06 Jul 2026 11:40:03 EDT news702552256 Modern wireless communication systems prefer higher frequencies to meet the growing demand for faster data transfer. The 300-GHz band, which lies near the lower end of the terahertz range, is a promising candidate for future sixth-generation (6G) wireless systems because it can support very high data rates and minimize atmospheric attenuation. However, using such high frequencies comes with major engineering challenges. Radio waves in this range suffer from severe free space path loss (FSPL), making signal transmission challenging over practical distances. https://techxplore.com/news/2026-07-compact-chip-based-transceiver-ultra.html Telecom Mon, 06 Jul 2026 10:10:01 EDT news702550614 An MIT-led research program aimed at creating future microsystems capable of sustainably transmitting data with greater bandwidth and higher efficiency than is possible today has made several significant advances since it was established in 2022. https://techxplore.com/news/2026-06-advance-greater-bandwidth-energy-efficient.html Electronics & Semiconductors Tue, 30 Jun 2026 17:20:06 EDT news702058081 Finland on Tuesday pulled the plug on analog landline phone calls after almost 150 years, the latest country to push forward in a global transition toward digital infrastructure. https://techxplore.com/news/2026-06-line-finland-analog-network.html Telecom Tue, 30 Jun 2026 12:50:02 EDT news702039730 Preventing adversaries from interfering with communications is crucial to national security.
