VCSEL arrays from Princeton Optronics for consumer electronics

Aug. 23, 2012
Designed for use in consumer electronic applications such as gesture recognition, natural user interface, and 3D content creation, a family of 800 and near-800 nm vertical-cavity surface-emitting laser (VCSEL) arrays have output powers from 100 mW to over 10 W.

In 3D image sensing, the VCSELs provide low speckle, sub-nanosecond rise and fall times, and >45% electrical-to-optical conversion efficiency. Chip sizes range from 0.5 × 0.5 to 3 × 3 mm2, depending on output power, and they operate at temperatures up to 80°C.

Princeton Optronics Announces Availability of 800 and Near 800nm VCSEL Illuminator Chips for Consumer Electronic 3D Sensor Applications

Princeton Optronics Inc. announces the availability of 800 and near 800nm Vertical Cavity Surface Emitting Laser (VCSEL) arrays with output powers from 100mW to over 10W peak power. These workhorse devices are designed for use in consumer electronic applications such as gesture recognition, natural user interface and 3D content creation where near infrared illumination is needed. In 3D image sensing, the VCSEL arrays provide very low speckle, sub-nanosecond rise and fall times, and high electrical-to-optical conversion (>45%) efficiency. They are highly suitable for time-of-flight (TOF) or structured light applications and are preferred to LEDs and edge emitting lasers because of their high efficiency, narrow and circular emission angle, short rise and fall times and flattop intensity profile. They also work at temperatures as high as 80degC. Today VCSELs are being made in large quantities ensuring both high reliability and competitive costs compared to light emitting diodes and conventional edge emitting lasers.

The chips 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. Chip sizes range from 0.5x0.5mm2 to 3x3mm2 depending on output power. Additionally, optics can be added to the package creating greater options for beam handling in the customer’s illumination system. Sample chips are immediately available at wavelengths in the 800nm region and additional wavelengths can be fabricated per custom request

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.
