I tend to think of myself as a comp-sci guy, and while I have a general idea of what this means and why it's awesome, it's still pretty hard for me to wrap my head around. Anyone wanna take a stab at explaining it? Because I am not confident enough to do so.

Of course, while the article says that these 'could be in the market within the next couple of years' - there is no guarantee. But IBM is looking to target super computers first, which will be pretty interesting considering that they have some pretty baller super computers of their own.

IBM has become the first company to integrate electrical and optical components on the same chip, using a standard 90nm semiconductor process. These integrated, monolithic chips will allow for cheap chip-to-chip and computer-to-computer interconnects that are thousands of times faster than current state-of-the-art copper and optical networks. Where current interconnects are generally measured in gigabits per second, IBMs new chip is already capable of shuttling data around at terabits per second, and should scale to peta- and exabit speeds.

The payoff makes all the hard work worthwhile, though. IBM now has a cheap chip that can provide a truly mammoth speed boost to computers. Its not too hyperbolic to say that this advancement will single-handedly allow for the continuation of Moores law for the foreseeable future.
In these chips, there are optical modulators and germanium photodetectors that can send and receive data at 25 gigabits-per-second (Gbps), using four-channel wave-division multiplexing (WDM).

While we couldnt even get a ballpark figure out of IBM, the use of a standard 90nm process means that these chips probably cost no more than a few dollars to produce. IBM is targeting super and cloud computing first, where bandwidth between nodes is a serious bottleneck but theres no reason that these chips wont eventually find their way into consumer hands.
...
This is the chip that could power the next-generation optical interconnect between your desktops CPU, GPU, and RAM. This is the chip that could directly wire your PC into your ISPs fiber-optic network, potentially unleashing terabit-or-higher download speeds. This chip is a big deal.
