Princeton Optronics, the recognized leader in high efficiency, high power VCSELs and VCSEL arrays, announces the availability of an ultra-high reliability, high power (8W) VCSEL array product with an efficiency of >40% at 60 deg C and a MTTF (Mean Time to Failure) of >100 years at an operating temperature of 70 deg C. This ultra-high reliability is achieved through improved device processing and a new chip on submount mounting technology. The device is directly surface-mountable on printed circuit boards (PCB) and suitable for high volume manufacturing.

A key application of this device is as an illumination source for 3D sensing or imaging in computers, tablets and cell phones. This VCSEL array can be used for either structured light or time-of-flight (ToF) applications. The high efficiency and high reliability of Princeton Optronics' VCSEL arrays make them preferred illumination devices for 3D sensing applications. Surface mounting makes them ideally suited for low cost high volume consumer electronics use.

Princeton Optronics recently won approval for two patents (US Patent 8,675,706B2 and 8,783,893B1) for surface mounted VCSELs for illumination applications, which makes them uniquely positioned for this market. The arrays can be packaged in a variety of configurations for high volume applications, very similar to LEDs. They do not require a hermetically sealed housing which reduces the packaging cost. Additionally, optics can be added to the package creating greater options for beam handling in the customer’s illumination system. Princeton Optronics is a manufacturer of high power single and multi-mode VCSELs and VCSEL arrays, and has a diverse line of products suitable for many applications including illumination, metrology, and solid state laser pumping.
