MEGGEN-LUCERNE, Switzerland -- LITRAX GmbH announces the introduction of an 850nm implant singlemode (SM) vertical-cavity surface-emitting Lasers (VCSEL) and laser bundles for applications requiring a reflected signal. These lasers are far superior in ESD (> 1 kV), reliability and performance to the oxide VCSELs that are presently sold and provide a cost and a design advantage including compact size, low-threshold current, allowing for lower power consumption, and superior output power with a tightly focused beam that enables the device to operate extremely accurately on many smooth surfaces.

“In the past 40 years the VCSEL has gone through a number of improvements that allow the user to expand the sensing capabilities of their products.” said Felix Stutz President of Litrax, “These 850 nm SM VCSEL are ideal for low cost sensing applications including laser mice, pointing devises, bar code readers and range finders. The array can be used for free space communication, IR lighting source for security, defense and many other IR sources.”

The inventor of this implant SM VCSEL, Prof. Y. J. Yang, Ph.D., a Full Professor in the Electrical Engineering Department, National Taiwan University, and a former researcher with Agilent, stated,” In my over two and a half decades of working with and developing lasers, these implant SM VCSEL devices are definitely the most advanced on the market today in terms of performance and reliability. VCSELs have moved beyond the telecommunications market and play an important role in I/O devices and many other applications.”
