Abstract :
It is our great pleasure to introduce a special ´Insight´ section in this issue containing six invited Insight Letters written by leading researchers in the rapidly-developing field of silicon photonics. There is currently great interest worldwide in finding ways to successfully integrate optoelectronic devices on a silicon chip, and we have certainly seen a diverse range of research activities in this area published in Electronics Letters over the last few years. Written by experts working at research institutions in the US, China, Europe and the UK, these letters offer the authors´ personal perspectives on the progress, future directions and potential applications of this technology. Together they paint a global picture of silicon photonics which we hope you will enjoy reading.
