VCSELs, short for Vertical Cavity Surface Emitting Lasers, are semiconductor-based light sources widely employed in diverse technological fields. These lasers offer unique advantages, including high power efficiency, compact size, and precise beam control. Their applications span from telecommunications and sensing to consumer electronics and automotive industries. VCSEL technology continues to evolve, driving innovations in data communication, 3D sensing, and emerging fields like augmented reality.

für your Application
VCSEL - Surface Emitting VCSEL Diodes
Vertical-Cavity Surface-Emitting Lasers are particularly popular for many applications.
Powerful Surface Emitters
Due to their reliability and high beam quality, VCSEL diodes (Vertical-Cavity Surface-Emitting Lasers) are particularly popular for many applications. Another important feature is the comparatively low temperature dependence of the emitted wavelengths. Upon customer request, the presented VCSELs are also available as high-performance arrays.

Supplier
VCSEL - VCSEL from visible to NIR
VCSEL laser diodes are offered with narrow linewidths (<0.1 nm) and visible to NIR wavelengths.
VCSELs from Firecomms
A range of VCSEL (vertical cavity surface emitting laser) laser diodes are supplied featuring narrow linewidths (<0.1nm), visible to NIR wavelengths, single longitudinal mode (SLM) and multiple longitudinal mode, generally lower output divergence to other edge-emitting lasers, higher production reliability due to in-line testing leading to generally lower pricing that is not possible with other laser chips tested after end of the production process, and typically with lower output power (<5mW) than DFB (distributed feedback) laser diodes offering otherwise similar spectral properties.
Typically supplied in TO-46 packages, with optional window forms or fibre coupled, these VCSELs suit small form factor or a low operating current, e.g. portable scanners. Additional applications include position sensing, medical devices and, of course, data transmission systems using glass or plastic optical fibres (POF).
