An ultrafast light-emitting device that can switch on and off 90 billion times a second was recently prototyped and demonstrated by engineers at Duke University.<\/a> \u00a0The device uses semiconductor quantum dots. \u00a0The goal of the research is to create a device that uses light photons instead of electronics to transmit data which will enable computers to operate at higher speeds.<\/p>\n

Similar research into the so-called ‘plasmonic materials’ is also happening at Purdue University. \u00a0Plasmonic materials can provide very high bandwidth at the nanometer scale.<\/p>\n

Nathaniel Kinsey<\/a>, doctoral student at Purdue, said that<\/a> “low power is important because if you want to operate very fast – and we show the potential for up to a terahertz or more – then you need low energy dissipation. \u00a0Otherwise, your material would heat up and melt when you start pushing it really fast. All-optical means that unlike conventional technologies we don’t use any electrical signals to control the system. Both the data stream and the control signals are optical pulses.”<\/p>\n

Kinsey\u00a0said that<\/a> “we are pretty far away from building anything resembling an processor. In fact our transistor is only simulation at the current time. \u00a0However, we have taken care to use realistic parameters so that the performance should be very similar to our simulations.”<\/p>\n

Great progress in 2015 — the International Year of Light<\/a>.<\/p>\n
