on-chip lasers that could be produced using the approach, concluding that: n particular, for on-chip optical interconnects, the demonstrated monolithic laser array,
together with the WDM technology, may finally pave the way to terascale computing. Photonic integrated circuits (PICS) based on the technology could dramatically change the architecture of fiber-optic transceivers used in data center optical interconnects, by pushing down the cost of chip-level data transfer between logic and memory devices.
That would in turn enable a radical scaling of a data center capacity, while simultaneously reducing increasingly colossal power demands with higher-efficiency data transfer.
Researchers say the lab-on-chip device is a step toward creating quantum computers that could help design new drugs,

including computer chips and other optoelectronic components.""Our results demonstrate relatively fast modulation from fundamentally slow phosphorescent light emitters,
One example could be optical communications networks on computer chips. Prototype on-chip networks have used semiconductor lasers as light emitters.
They can modulate very quickly, but they have downsides. Semiconductors can't be grown directly on a silicon chip,
for example--makes for bulky systems that take up a lot of real estate on a chip. What's more, semiconductor lasers are not particularly efficient.
There's still more work to be done to get such a system up to a speed that would be useful on a chip,

which means they now have the ability to build the world's first quantum processor chip and, eventually, the first silicon-based quantum computer.
Right now, regular computer chips store information as binary bits, which are either in a 0 or 1 state.
"Because we use essentially the same device technology as existing computer chips, we believe it will be much easier to manufacture a full-scale processor chip than for any of the leading designs,
which rely on more exotic technologies, "project leader Andrew Dzurak said in a press release.""This makes the building of a quantum computer much more feasible,
The team overcame this by effectively copying the setup of traditional chips. In that setup, binary bits are defined by tiny semiconductor devices known as transistors.

the researchers have demonstrated a monolithically-cooled chip that can operate at temperatures more than 60 percent below those of similar air-cooled chips.
The cooling comes from simple deionized water flowing through microfluidic passages that replace the massive air-cooled heat sinks normally placed on the backs of chips."
"Supported by the Defense Advanced Research Projects Agency (DARPA), the research is believed to be the first example of liquid cooling directly on an operating high-performance CMOS chip.
