This is very exciting announcement...perhaps photonic interconnects will see commercial applications finally...if anyone from ST or Luxter is interested in presenting at CMOS Emerging Technologies in Vancouver in July (www.cmoset.com) pls contact me at firstname.lastname@example.org
I believe that Intel continues to invest heavily in this technology, this is the future, photons are faster than electrons...the only debate is when it will be deployed commercially not whether it will be deployed...Kris
I am pretty sure that photon is smaller than silicon chip @me (assuming you can isolate one and measure how large it is which is rather impossible according to quantum physics)....but putting size deliberations aside the discussion should be around a point "how long the interconnect has to be in order for optical transmission to make sense?"...that number used to be several km (long haul optical fibers) and it is now several cm (optical back-planes)...so likely it will become several mm in the future at which point application on chips might make sense...Kris
I guess we were on different pages @me...I am slowly understanding what you are saying...you are comparing light wavelength with MOSFET channel size...yes, photon is larger in that sense, and it leads to a statement that photonic devices will be probably always larger then electronic one...so yes photodiode on silicon will be always larger than transistor...but the signal from laser or modulator going to a photodiode will be send much faster than from transistor to transistor (if they are far away enough) and that is a main point of photonic interconnects on chip...Kris
theres so much to say on this nano photonics subject it fascinates me :)
but its hard to cut through the crud and pull out the gems in general reporting not least when we will actually see a group of products you can buy and play with.
i prefer to look at the core device or process they are describing and think how one might put that and related findings to practical use to make an exact copy of what's already available in the normal scale only nano scale in this case.
i dont want to see this simply as "smarter wire" or so different that people think it needs a totally different wat of doing things, for instance the "omparing light wavelength with MOSFET channel size" im not quite sure what that means but this pic overcomes that i think ?
see http://www.spacemart.com/nanotech.html for many other things they can do and how you might use them to make a 3d stacked SOC etc
"Nano-coating doubles rate of heat transfer" seems obvious,out that and a nano thermoelectric generator in layers to both cool and reclaim power to supplement local power nano ram.
"weld nanowires with light"
and lots more
"Metal nanoparticles shine with customizable color" for laser.
"Light-emitting nanocrystal diodes go ultraviolet"
i think in interesting as the wavelengths of 1310-nm, 1490-nm and 1550-nm above imply they are ONLY thinking generic Wavelengths Fiber Optics in the infrared range over glass not the lower UV range Plastic optical fiber (POF)at 650 nm.
odd in so far as nano plastics and so called bio chips are available today, so its perfectly possible to combine these and the other nano processes into one assembly and see the damn things ASAP LOL, did i say there's lots to say :)
