Before silicon photonics can fulfil its commercial potential – providing low-cost, high-speed optical devices for connecting servers and switches inside data centres – it must overcome many challenges. One is getting the chips made. The technology is well established, but the manufacturing processes have yet to reach a level of maturity sufficient to enable silicon photonics to make a seamless transition to industrial-scale production.
Cost and compatibility can make a compelling case for pushing 100Gb/s bandwidth over a single optical channel, both as individual links and supporting 400Gb/s Ethernet, finds Andy Extance
Robin Mersh takes a look at how the industry is creating next-generation optical access fit for 5G
Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang
