Multimode VCSELs with stable, advanced, linear polarization improve exposure quality and the resolution in demanding 3D lighting application, e.g. in OLED displays.
The surface grating enables stable polarization and is etched directly into the GaAs. Due to the optimized grid design, the polarized VCSELs achieve nearly 100 percent power efficiency compared to non-polarized VCSELs. TRUMPF has developed the patented technology of VCSELs with stable polarization for large-scale applications.
Multimode VCSEL
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.
Just under two 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.

LiDAR
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
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.

Illumination
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.

OLED displays
VCSELs with stable and linear polarization improve exposure quality and the resolution in demanding 3D lighting application, e.g. in OLED displays.
