High-speed VCSELs for next-generation telecommunications links

High bit rate communication links are placing increasing demands on the performance and cost of semiconductor laser diodes. VCSELs are uniquely suited to meeting the requirements of 10 Gb/s and higher applications. The laser requirements include high temperature operation, high bandwidth, high reliability, short rise and fall times, low RIN, low jitter, low RMS linewidth, and drive circuit compatibility. We will discuss the major challenges to achieving these goals as well as approaches that have been successful to date.
