U-L-M Photonics GmbH is a leading supplier of advanced Vertical Cavity Surface-Emitting Lasers (VCSELs) These devices are available from 760 to 980 nm and are used in many telecom and sensing applications. Low cost single-mode devices are now in high volume production. Microsoft has delivered over 2.5 million of the high definition Laser Mouse 6000 and has again chosen U-L-M Photonics to be the supplier for their next generation product.
