Multimode VCSELs are infrared light sources for mobile consumer applications. The compact dimensions allow use of the laser diodes in highly integrated sensors. These laser diodes are ideally suited for time-of-flight distance sensors due to their power class and radiation characteristics.
Mesas in parallel operation result in redundancy and increase operational safety.
Light at 940 nm cannot be perceived by the human eye.
Benefit from a very fast pulsing mode due to short rise/fall times.
More than 1.5 billion VCSELs used without any failures.
Distance sensor system
The compact 940 nm laser diode is perfectly suitable for ranging applications, such as proximity or laser focusing in smartphones.
VCSEL arrays are excellent for LiDAR applications. Very low rise and fall times of the optical pulses make ultrashort pulses with high peak power possible. The addressability of the different segments on the VCSEL arrays can significantly improve the system performance.
Structured light applications can be addressed very well with VCSEL arrays as the light source. Processing at wafer level with the latest semiconductor processing systems enables the smallest spacing and individual arrangements of emitters.
Multimode VCSEL arrays are perfect light sources for IR lighting. The low spectral range and outstanding power across a temperature interval enable very good system performances.

ViBO stands for VCSEL integrated Backside Optics. This is an advanced, cost-effective and easy-to-integrate VCSEL array technology with monolithically integrated micro-optical elements. The platform offers a top view that is 5 times smaller compared to other packaged VCSEL solutions. Furthermore, the integrated optics enable an inherently eye-safe system throughout the entire product life cycle. ViBO solutions are particularly interesting for 3D sensor applications in the areas of consumer electronics, automotive and other industrial sectors.
