I asked Imec about the 28Gb/s rating and got this response referring to 400 Gb/s: "Imec's announcement is about the co-integration of modulators and photodetectors with improved performance, enabling 28 Gb/s bit rates per (wavelength) channel. In addition, we also reported compact and thermally tunable WDM filters with high power efficiency. These building blocks can be combined to realize compact, WDM-enabled Si Photonics transceivers with aggregate bandwidths of 400 Gb/s and more."
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
