with 18 billion connected devices by 2019 the internet of everything will soon require 1.4 zettabyte of global data transfers per day and the internet lives in the data center that keep evolving continuously to follow the data transfers growth rate constantly pressing for more real estate and power consumption as 75% of the total data movement happens within the data centers active optical cables have emerged to interconnect all these thousands of computer notes in abling low-power high-density interconnection even so next-generation exascale systems will require roughly a billion of optical links how can we solve that to drastically address the interconnection needs of near future high-performance computers and data centers nine partners around Europe have joined forces under the european research project horizon 2020 ICT streams the streams will rely on wavelength division multiplexing technology to implement transceivers with unprecedented speeds and will exploit the diverse channel colors to route the data across the cpus furthermore to dramatically save on space and power streams will embed the optical transceivers onboard and will develop a whole new class of polymer-based electro-optical circuit boards to simultaneously route both optical and electrical signals on the same board the polymer layer will also allow for simplifying chip assembly and board manufacturing processes optics unlike electronics require precision alignment of the optical beam and this is a major bottleneck for their large-scale deployment streams aims to enable a single step assembly process relaxing manufacturing time and cost by simply placing the silicon waveguide on top of the polymer waveguide streams will rely on advanced electronics and silicon photonics to implement power efficient 50 gigabits per second line rate multi-channel WDM transceivers equipped with a novel non-invasive monitoring technique called clip to make silicon photonics devices reliable in the harsh environments of real-life data centers but silicon is not capable to emit light streams aims to add the active material layer through wafer bonding in order to achieve CMOS compatible process allowing for the first time in plane lasers to be developed in CMOS boundaries finally streams aims to radically reshape the optical links to incorporate advanced wavelength routing functionalities by introducing a novel amplification scheme based on electrically pumped photonic crystal amplifiers in a nutshell streams will drastically boost photonics performance but the ultimate project goal is to develop the technology pack that will allow their massive deployment on computer boards
