The TRUMPF technology platform ViBO – VCSEL with integrated Backside Optics - revolutionizes the VCSEL technology for sensing and illumination applications. The idea of ViBO is to integrate all relevant functions, provided nowadays by an extra package, directly into the VCSEL chip. ViBO is characterized by lenses which are directly etched into the GaAs substrate. This enables a breakthrough in miniaturization. At the same time the lenses enabling extraordinary freedom of design for optical designers. The optics are monolithically integrated on wafer level, what guarantees life-long laser safety and renounce additional interfaces. The product platform allows tailored illumination for consumer or automotive applications and enables the addressability of multiple zones on a chip.
