Hasta La Gadget!

Antennas have often capped the potential speed of a wireless link — the 450Mbps in modern 802.11n WiFi routers is directly linked to the use of a MIMO antenna array to catch signals more effectively, for example. That ceiling is about to get much higher, if A*STAR has anything to say about it. The use of a polymer filling for the gaps instead of air lets the Singapore agency create a 3D, cavity-backed silicon antenna that measures just 0.06 by 0.04 inches, roughly the size of a seed on your hamburger bun, even as it increases the breakneck pace. The new antenna generates a signal 30 times stronger than on-chip rivals at an ultrawideband-grade 135GHz, and musters a theoretical peak speed of 20Gbps — enough that 802.11ac WiFi’s 1.3Gbps drags its heels by comparison. Before we get ahead of ourselves on expecting instant file transfers at short distances, there’s the small matter of getting a chip that can use all that bandwidth. Even the 7Gbps of WiGig wouldn’t saturate the antenna, after all. Still, knowing that A*STAR sees “immense commercial potential” in its tiny device hints that wireless data might eventually blow past faster wired standards like Thunderbolt.

Imaging has been defined by glass lenses for centuries, and even fiber optics haven’t entirely escaped the material’s clutch. Harvard’s School of Engineering and Applied Sciences might have just found a way to buck those old (and not-so-old) traditions. A new 60-nanometer thick silicon lens, layered with legions of gold nanoantennas, can catch and refocus light without the distortion or other artifacts that come with having to use the thick, curved pieces of glass we’re used to — it’s so accurate that it nearly challenges the laws of diffraction. The lens isn’t trapped to bending one slice of the light spectrum, either. It can range from near-infrared to terahertz ranges, suiting it both to photography and to shuttling data. We don’t know what obstacles might be in the way to production, which leads us to think that we won’t be finding a gold-and-silicon lens attached to a camera or inside a network connection anytime soon. If the technology holds up under scrutiny, though, it could ultimtately spare us from the big, complicated optics we often need to get just the right shot.

Chipzilla didn’t get its position as the king of semiconductors by twiddling its thumbs, folks. It became a Valley behemoth by delivering us faster and better silicon, and its latest $4.1 billion purchase — a 15 percent stake in silicon manufacturing equipment maker ASML Holding NV — should help keep Intel atop the CPU heap. You see, Intel’s in the process of retooling its chip manufacturing process to use bigger diameter silicon wafers, which’ll make those Ivy Bridge, ValleyView and other future chips cheaper for all of us. Such retooling can take years to implement, which is likely why Intel was willing to plunk down so much cash to ensure nothing futzes with its manufacturing timetable. The company’s investment will presumably give it the clout to get ASML’s crucial lithography equipment on the fast track to completion. Hop to it, fellas, we want our CPUs at bargain-basement prices, and we want them now.
