Single-mode VCSEL at 760 and 948 nm
Large production quantities allow for the replacement of an LED by a single-mode laser.
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.
An alternative application that, until now, could only be served by an HeNe laser.
