Selection Guide for Bestselling Relay-Protected Vertical Cavity Surface Emitting Lasers
An application area which was developed later, but has acquired a large market volume, is that of computer mice. A laser mouse with a VCSEL as light source can have a high tracking precision combined with a low electricity consumption, as is important for battery-powered devices.Due to the short resonator round-trip time, VCSELs can be modulated with frequencies well in the gigahertz range. This makes them useful as transmitters for optical fiber communications and for free-space optical communications. For short-range communications, 850-nm VCSELs are used in combination with multimode fibers. A data rate of e.g. 10 Gbit/. VCSELs can also be used in miniature optical clocks, where the laser beam probes an atomic transition in cesium vapor. Such clocks could become part of compact GPS devices.Due to their high output powers, VCSEL arrays can often compete with diode bars (partially even with diode stacks), e.g. for pumping solid-state lasers.
