Virus-size Plasmon Nanolaser
| Quote: | A Northwestern University research team developed a process to manufacture single laser devices the size of a virus particle which operate at room temperature. These plasmonic nanolasers may readily integrate into silicon-based photonic devices, all-optical circuits and nanoscale biosensors.
Size reduction of photonic and electronic elements is critical piece in future development of ultra-fast data processing and ultra-dense information storage. The miniaturization of a such a key, workhorse instrument — the laser — is a major step.
“Coherent light sources at the nanometer scale are important not only for exploring phenomena in small dimensions but also for realizing optical devices with sizes that can beat the diffraction limit of light,” said Teri Odom, a nanotechnology expert who led the research.
Odom is the Board of Lady Managers of the Columbian Exposition Professor of Chemistry in theWeinberg College of Arts and Sciences and a professor of materials science and engineering in the McCormick School of Engineering and Applied Science.
“The reason we can fabricate nano-lasers with sizes smaller than that allowed by diffraction is because we made the lasing cavity out of metal nanoparticle dimers — structures with a 3-D ‘bowtie’ shape,” Odom said.
These metal nanostructures support localized surface plasmons — collective oscillations of electrons — that have no fundamental size limits when it comes to confining light.
The use of the bowtie geometry has two significant benefits over previous work on plasmon lasers: (1) the bowtie structure provides a well-defined, electromagnetic hot spot in a nano-sized volume because of an antenna effect, and (2) the individual structure has only minimal metal “losses” because of its discrete geometry.
“Surprisingly, we also found that when arranged in an array, the 3-D bowtie resonators could emit light at specific angles according to the lattice parameters,” Odom said. |

| So in future, when the air and drinking water is swarming with nanobots, do you stop being a person in legal sense and become a country? Do nanobots need a passport? |

yes and it has to be check card size.

I want a bunch of these scouring the crud off the insides of my blood vessels. It would suck if they went haywire, though, and started erasing my brain.

just upload your brain to the cloud first. I am sure amazon or google would take good care of your personality. Only planting advertisement into your core self that really suits you.

Better than ads, It's the Nexus Stem: a Dynamically Optimized Nascent Obsolescence Enabling Vertical Integration Layer.

DONOEVIL, eh? 
Can you come up with an acronym for the Google-Enhanced MESENCEPHALON?
Midbrain-Embedded Sensory Enchancing Nano-Carbon Extra-Pituitary Hydrodynamic-Actuating Layer Of Nanobots

I like the reuse of mid-brain. I doubt I could come up with a better version, so I'm not even going to try that many letters :D
BUT, Mesencephalon is to Stem as IEEE 1394 is to FireWire :P

Actually, Mesencephalon is to Brainstem stem as Southbridge is to Super I/O Controller.

Not Brainstem stem, Nexus Stem. Poor marketing vs. good marketing.

Okay, but I was assuming the Nexus Stem would be an augmentation or replacement of the brainstem.

:D Since when does marketing have to do with actual function?

 Hope it doesnt have some kind of DRM scheme or something. |

This prompts a question according to political philosophy, what is prefered;
a.) government/corporate DRM in your brain
b.) shady 3rd party hacking away the DRM
Whom do you trust, baby?  |

My own code. Simple and stupid as it may be, it's not uploading my credit card and personal data to the Ukraine.

Cave Johnson here. The Sentient Cloud is still waiting for one of you to upload his brain. If I were you, I'd volunteer quickly before we're all infested with plasmonic nanolasers that eat brain cells to punish us for having blasphemous thoughts against the Sentient Cloud.
