ViBO is a VCSEL array technology based on TRUMPF high-performance VCSELs and integrates monolithically integrated micro-optical elements. Lens structures according to specific customer requirements are etched directly into the top surface of the GaAs substrate to create the desired lighting profile, such as scattering or collimation. Moreover, more sophisticated lighting profiles can also be created by addressing different zones.
ViBO: VCSEL with integrated Backside Optics
ViBO is a VCSEL array technology based on TRUMPF high-performance VCSELs. It involves etching unique, patented lens forms, directly into the GaAs substrate. The VCSEL array technology features monolithically integrated micro-optical elements and provides suppliers with unique advantages in creating customized lighting profiles for use in their advanced 3D sensor systems. The technology supports a new generation of lighting devices that are inherently eye-safe, for example, because the diffuser optics are monolithically integrated into the laser array. Furthermore, the components are easy to mount on the PCB or driver IC via preformed contacts using SMD assembly. This significantly reduces the form factor compared to previous hybrid, packaged VCSEL solutions which also enables easier integration, for example, under smartphone displays.
3D sensor systems
ViBO technology is ideal for use in 3D sensor systems due to its flexibility in creating individual lighting profiles and ability to address different lighting zones on a chip. ViBO supports 3D sensor systems applications such as object or person identification, facial recognition, license plate recognition, security and access control, mobile payment, autonomous driving, driver monitoring, gesture recognition and machine vision.
ViBO technology with integrated optics creates lighting profiles to image objects at both close and long ranges. This is precisely what is needed for LIDAR. The small form factor allows VCSEL components to be easily integrated into system designs.
