What is silicon photonics?

0

Silicon photonics is an evolving technology in which data is transferred among computer chips by optical rays. Optical rays can carry far more data in less time than electrical conductors. The concept involves combining laser and silicon technology on the same chip. The improved performance results from the greater available bandwidth and higher propagation speed of infrared (IR) beams compared with electric current. The effective implementation of silicon photonics technology would dramatically increase the processing speed and power of computers. Silicon photonics research began in the late 1980s and has been ongoing ever since. Historically, one of the most serious challenges facing the developers of silicon photonics has been the fact that laser devices, which generate the IR beams that carry the data, are power-hungry. In addition, silicon has not proven effective for lasing because of thermal dissipation within the material. For these reasons, external lasers have been required i
