Description

2W 860nm 850nm VCSEL-array Laser Diode

The vertical-cavity surface-emitting laser, or VCSEL, is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer. VCSEL applications include fiber optic communications, precision sensing, computer mice and laser printers.

850nm VCSELs from ushio

We offer a variety of standard Vertical Cavity Surface Emitting Lasers (VCSELs) in ready to use fiber coupled packages. Packaging options include Receptacle style housings such as ST, FC and SC as well as fiber pigtailed co-axial assemblies. VCSELs are typically used with multi-mode optical fiber and may be specified for coupling to 50 um , 62.5 um or 100 um core optical fibers. VCSELs may also be fiber coupled to single mode fibers with 5, 7 or 9 um core diameters. Units built with fiber pigtails are available terminated with optical connectors. Specialty fiber sizes may be available upon request

VCSELs are used for communication links to 500 meters in networks, enterprise and data centers. The technology has served the data communications industry for more than 10 years. VCSEL is an emerging technology for many applications including chip to chip interconnect, touchless sensing and gesture recognition.
