Vertical-cavity surface-emitting lasers (VCSELs) have various advantages over other types of lasers. These include:
- surface emission, which offers design flexibility in addressable arrays
- low temperature dependence of the lasing wavelength
- superior reliability
- a wafer-level manufacturing process
These features make VCSELs better suited to a wide range of applications than conventional edge-emitting diode lasers and LEDs.
The ams VCSEL technology includes the epitaxial structure and chip design, epitaxial growth, front- and back-end processing, packaging and advanced testing and simulations. ams VCSELs are rated for operation at ambient temperatures as high as 150°C.
