so the simpsons were on to something with "speed holes"
Are these holes supposed to act in a similar fashion to Myelin sheath cells along an axon in a nerve cell? Because that would be brilliant if that sort of organic design started to make its way into electronics/computing.
IBM built the chip using standard parts so it can make its way to market relatively quickly. "The heart of the chip is a single CMOS, plain-Jane unmodified process chip," Schow said. "That base chip has all the electronic circuit functions to complete the optical link. So it's got drivers that modulate vertical cavity lasers and receiver circuits that convert photocurrent from a detector into a usable electrical signal."
From Raffin's post / quote:
Thats why the holes are there, without them, the photodiode array would be completely blocked from the flip-chip soldering to this chip. With the holes, the light signals going in and out of the photodiode array that is basicly sandwitched up to this chip can pass right thru unblocked.
And by doing a flip-chip mounting to the photodiode array, the interconnects between the 2 devices are basicly next to nothing (and no parasitic capacitance), which is how they are able to get the speed to such rediculous levels and still have very good power use.
I would like to know how it works, my guess is optical wavelength tuning, much the same principle as RF tuning in radar array antennae.
Stop with the bullshit already please!
If the average bluray has 20GB of movie data then it can do ~50 movies per second, which means the article was only off by one decimal place, which is probably a simple typo that you dolts just can't seem to stop making a big deal of.

Actually, 1Tbps would handle about twelve 20GB movies per second, not counting overhead.
Rethink your math, it's off a bit.
You guys are right, I wasnt thinking of bytes to bits 1/8.
Then again, they never claimed it was blu ray quality HD movies did they? Maybe they are talking about 500 hulu or youtube type hi def videos per second...lol
