Researchers at Intel and the University of Santa Barbara have announced the worlds first Hybrid Silicon Laser, or HSL. An HSL is a silicon-based laser emitting device. According to Intel, creating a laser emitting silicon chip is a breakthrough that will propel the world of computers into the light-based transmission era.
The new laser chip is made of a material called Indium Phosphide, and it contains properties that allow it to emit light when voltage is applied. According an Intel Chief Technology officer Justin Rattner "Silicon Photonics is a critical part of tera-Scale computing as we need the ability to move massive amounts of data on and off these very high performance chips"
The possibilities surrounding the new technology are certainly very exciting. As we edge closer to the physical limits of traditional silicon, HSL provides an medium for the communications and computing industries to move huge volumes of data at a faster rate.

The difference is actually more in the motor. It gives better head (no pun) but as a result consumes more power and is slightly noisier.
