05.14.25 -- Neuromorphic Computing Breakthrough, Improving Signal To Noise Ratio & More

3 weeks ago | photonicsonline.com | John Oncea |James Mackay |Melles Griot |Emily Newton

Neuromorphic computing uses principles from neuroscience to create devices that mimic neural systems, achieving efficient brain-like processing. It combines photonics and neuromorphic architectures for high efficiency and connectivity. More Signal, Less Background: Improving Signal To Noise RatioThe path to improving signal-to-noise ratio - the ratio of the power of signal (desired input) to the power of background noise (undesired input) - is to reduce the power of the noise – less background.
Fiber Optic Cables: How Far Is Too Far?

3 weeks ago | photonicsonline.com | John Oncea

By John Oncea, Editor With ideal conditions and amplification, optical fiber can transmit petabit speeds globally, but real-world limits depend on fiber type and network design. Given perfect conditions in a lab-like setting without ensuring no signal degradation, how far could fiber optics transmit data? Hundreds of miles? Thousands? Well, we don’t live in a lab-like setting.
