VCSEL

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.

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).
