OPV200 VCSEL

Vertical Cavity Surface Emitting Lasers (VCSELs)

In contrast to conventional laser diode technology, these laser diodes emit upward, hence the name Vertical-Cavity Surface-Emitting Lasers. Long wavelength VCSELs have cost advantages over traditional edge-emitting laser diodes, and are capable of transmitting high data transfers over long distances. Other benefits include lower power consumption and higher reliability.

TT Optek offers a range of 850nm VCSELs for data communications and sensing applications.

VERTILAS' newly-developed laser diodes (1310, 1490 and 1550nm) stand out for their high-speed data transfer capabilities (up to 10 Gbit/s), as well as for their small structural shape, low current threshold and low power consumption. Long wavelength VCSELs constitute a core component of future laser-optic communication networks through which fiber-to-the-home plans are being made possible for the first time in a cost-effectiveness manner. They also offer numerous applications for use in gas sensor engineering and optical measuring methods.
