VCSEL

VCSELs. Vertical cavity surface emitting lasers are inexpensive lasers with low power consumption. They are used in absorption spectroscopy, optical PC mouse applications, and data transmission in optical fibers.

Singlemode VCSEL for Spectroscopic Applications

Single-mode VCSEL at 760 and 948 nm

Singlemode VCSELs for Pointing and Position Sensing

Large production quantities allow for the replacement of an LED by a single-mode laser.

Single-mode VCSELs for Atomic Clock Pumping

Single-mode VCSELs are key components in the manufacture of miniaturized rubidium or cesium atomic clocks. The idea is a wrist-worn atomic clock based on MEMS technology.
