VCSELs Fundamentals Technology and Applications of **-Emitting Lasers 2013

Springer-Verlag Berlin Heidelberg 2013 VCSEL 垂直腔面发射激光器 Vertical Cavity Surface Emitting Laser Vertical-cavity surface-emitting lasers (VCSELs) are firmly established in the laser diode market for about 15 years meanwhile. It took about 17 years before these devices were commercialized. Multimode fiber optical networks with data rates in the 1 Gbit/s range were the initial market. In 2004, VCSELs were first incorporated in optical computer mice. Today, these two application areas approximately equally share a production volume of almost 100 million units per year. In future, high volumes can be expected also, e.g., for diverse sensing and illumination purposes, the latter using high-power laser arrays.
